e46287853f3a41c3f0772d3448d8df4ea01a156f build: remove --enable-determinism configure option (fanquake)
Pull request description:
This was added by me a while back, with the intention of expanding what this did. That hasn't happened, and this hasn't gained much use. There's also been some discussion of some configure option fatigue, so just remove it for now. Note that `-Wl,--no-insert-timestamp` is also already used in the Guix build.

8f7704d0321a71c1691837a6bd3b4e05f84d3031 build: improve detection of eBPF support (fanquake)
Pull request description:
Just checking for the `sys/sdt.h` header isn't enough, as systems like macOS have the header, but it doesn't actually have the `DTRACE_PROBE*` probes, which leads to [compile failures](https://github.com/bitcoin/bitcoin/pull/22006#issuecomment-859559004). The contents of `sys/sdt.h` in the macOS SDK is:
```bash
#ifndef _SYS_SDT_H
#define _SYS_SDT_H
/*
* This is a wrapper header that wraps the mach visible sdt.h header so that
* the header file ends up visible where software expects it to be. We also
* do the C/C++ symbol wrapping here, since Mach headers are technically C
* interfaces.
*
* Note: The process of adding USDT probes to code is slightly different
* than documented in the "Solaris Dynamic Tracing Guide".
* The DTRACE_PROBE*() macros are not supported on Mac OS X -- instead see
* "BUILDING CODE CONTAINING USDT PROBES" in the dtrace(1) manpage
*
*/
#include <sys/cdefs.h>
__BEGIN_DECLS
#include <mach/sdt.h>
__END_DECLS
#endif /* _SYS_SDT_H */
```
The `BUILDING CODE CONTAINING USDT PROBES` section from the dtrace manpage is available [here](https://gist.github.com/fanquake/e56c9866d53b326646d04ab43a8df9e2), and outlines the more involved process of using USDT probes on macOS.

584fd91d2d294883e6896dbd64a2176528e94581 init: only use pipe2 if availabile, check in configure (Sebastian Falbesoner)
Pull request description:
The result of the O_CLOEXEC availability check is currently only set in the Makefile and passed to LevelDB (see `LEVELDB_CPPFLAGS_INT` in `src/Makefile.leveldb.include`), but not defined to be used in our codebase. This means that code within the preprocessor conditional `#if HAVE_O_CLOEXEC` was actually never compiled. On the master branch this is currently used for pipe creation in `src/shutdown.cpp`, PR #21007 moves this part to a new module (I found the issue while testing that PR).
The fix is similar to the one in #19803, which solved the same problem for HAVE_FDATASYNC.
In the course of working on the PR it turned out that pipe2 is not available an all platforms, hence a configure check and a corresponding define HAVE_PIPE2 is introduced and used.
The PR can be tested by anyone with a system that has pipe2 and O_CLOEXEC available by putting gibberish into the HAVE_O_CLOEXEC block: on master, everything should compile fine, on PR, the compiler should abort with an error. At least that's my naive way of testing preprocessor logic, happy to hear more sophisticated ways :-)

Pull request description:
This PR removes the `--enable-upnp-default` and `--enable-natpmp-default` options from configure.
It's odd to me that we maintain configure-time options for setting the default port-forwarding runtime state (but no other similar options), and I'm not sure what use-case it satisfies, that can't be achieved by multiple other means. I also doubt that we'll ever restart using these in release builds, or turning on any of this by default.
I think the only scenario these options would be used is when you want to compile your own binaries (we don't use them in Guix), with port-forwarding on by default, but otherwise can't or don't want to use a `.conf` file, can't or don't want to pass command line options at runtime, and also don't want to modify the source code?

4446ef0a549d567a88d82b606aa8c47f115673f9 build: remove support for weak linking getauxval() (fanquake)
e56100c5b4daf2285dde9807bf654599aa19bd6b build: remove arm includes from getauxval() check (fanquake)
Pull request description:
It was [pointed out in #23030](https://github.com/bitcoin/bitcoin/pull/23030#issuecomment-922893367) that we might be able to get rid of our weak linking of [`getauxval()`](https://man7.org/linux/man-pages/man3/getauxval.3.html) (`HAVE_WEAK_GETAUXVAL`) entirely, with only Android being a potential holdout:
> I wonder if it's time to get rid of HAVE_WEAK_GETAUXVAL. I think it's confusing. Either we build against a C library that has this functionality, or not. We don't do this weak linking thing for any other symbols and recently got rid of the other glibc backwards compatibility stuff.
> Unless there is still a current platform that really needs it (Android?), I'd prefer to remove it from the build system, it has caused enough issues.
After looking at Android further, it would seem that given we are moving to using `std::filesystem`, which [requires NDK version 22 and later](https://github.com/android/ndk/wiki/Changelog-r22), and `getauxval` has been available in the since [API version 18](https://developer.android.com/ndk/guides/cpu-features#features_using_libcs_getauxval3), that shouldn't really be an issue. Support for API levels < 19 will be dropped with the NDK 24 release, and according to [one website](https://apilevels.com/), supporting API level 18+ will cover ~99% of devices. Note that in the CI we currently build with NDK version 22 and API level 28.
The other change in this PR is removing the include of headers for ARM intrinsics, from the check for strong `getauxval()` support in configure, as they shouldn't be needed. Including these headers also meant that the check would basically only succeed when building for ARM. This would be an issue if we remove weak linking, as we wouldn't detect `getauxval()` as supported on other platforms. Note that we also use `getauxval()` in our RNG when it's available.
I've checked that with these changes we detect support for strong `getauxval()` on Alpine (muslibc). On Linux, previously we'd be detecting support for weak getauxval(), now we detect strong support. Note that we already require glibc 2.17, and `getauxval()` was introduced in `2.16`.
This is an alternative / supersedes #23030.

0660119ac372c2863d14060ac1bc9bc243771f94 Drop unintended bitcoin-tx dependency on libevent (Russell Yanofsky)
Pull request description:
This fixes compile errors trying to build bitcoin-tx and bitcoin-wallet without libevent, which were reported by Luke Dashjr in https://github.com/bitcoin/bitcoin/issues/18465
The fix avoiding `bitcoin-tx` dependency on libevent just adds a conditional build rule. This is implemented in the first commit (more details in commit description).
The fix avoiding `bitcoin-wallet` dependency on libevent requires minor code changes, because `bitcoin-wallet` (unlike `bitcoin-tx`) links against code that calls `urlDecode` / `evhttp_uridecode`. This fix is implemented in the second commit (again details in the commit description).

## Issue being fixed or feature implemented
The order of members in a class/struct definition and the order of their
initialization should match. This ensures that the code is more
error-proof in cases where the order of member initializations is
important, as they may depend on each other.
Instead manual checking of member initialization better let CI handle
it.

6cef3652d143a1dddad1254cab0953561d24c1fa build: fix -Wformat-security check when compiling with GCC (fanquake)
Pull request description:
GCC expects `-Wformat` to be passed with [`-Wformat-security`](https://gcc.gnu.org/onlinedocs/gcc/Warning-Options.html), which means
when we test for it in configure it currently fails:
```bash
checking whether C++ compiler accepts -Wformat-security... no
...
configure:15907: checking whether C++ compiler accepts -Wformat-security
configure:15926: g++ -std=c++11 -c -g -O2 -Werror -Wformat-security conftest.cpp >&5
cc1plus: error: '-Wformat-security' ignored without '-Wformat' [-Werror=format-security]
cc1plus: all warnings being treated as errors
```
and never gets added to our CXX flags. Note that Clang does not have this requirement and the check is working correctly there.
The change in this PR is the simple fix, however we might want to consider using something like `-Wformat=2` in future, which in GCC is equivalent to `-Wformat -Wformat-nonliteral -Wformat-security -Wformat-y2k.` and similar [in Clang](https://clang.llvm.org/docs/DiagnosticsReference.html#wformat-2).

5d4999951ee32e333b511245862628e80f83b703 prevector: Avoid unnamed struct, which is a GNU extension (DesWurstes)
Pull request description:
Since we [started using](https://github.com/bitcoin/bitcoin/pull/7165) the `ax_cxx_compile_stdcxx.m4` macro we've been passing `[noext]` to indicate that we don't want to use an extended mode, i.e GNU extensions. Speaking to Cory he clarified that the intention was to "require only vanilla c++11 and turn _off_ extension support so they would fail to compile".
However in the codebase we are currently making use of some GNU extensions. We should either remove there usage, or at least amend our CXX compiler checks. I'd prefer the former.
#### anonymous structs
```bash
./prevector.h:153:9: warning: anonymous structs are a GNU extension [-Wgnu-anonymous-struct]
struct {
```
This is fixed in b849212c1e.
#### variadic macros
```bash
./undo.h:57:50: warning: must specify at least one argument for '...' parameter of variadic macro [-Wgnu-zero-variadic-macro-arguments]
::Unserialize(s, VARINT(nVersionDummy));
```
This is taken care of in #18087.
The `LOG_TIME_*` macros introduced in #16805 make use of a [GNU extension](https://gcc.gnu.org/onlinedocs/cpp/Variadic-Macros.html).
```bash
In file included from validation.cpp:22:
./logging/timer.h:99:99: warning: token pasting of ',' and __VA_ARGS__ is a GNU extension [-Wgnu-zero-variadic-macro-arguments]
BCLog::Timer<std::chrono::milliseconds> PASTE2(logging_timer, __COUNTER__)(__func__, end_msg, ## __VA_ARGS__)

BCLog::Timer<std::chrono::seconds> PASTE2(logging_timer, __COUNTER__)(__func__, end_msg, ## __VA_ARGS__)
^
6 warnings generated.
```
This is fixed in 081a0ab64eb442bc85c4d4a4d3bc2c8e97ac2a6d and 612e8e138b97fc5ad2f38847300132a8fc423c3f.
#### prevention
To ensure that usage doesn't creep back in we can add [`-Wgnu`](https://clang.llvm.org/docs/DiagnosticsReference.html#wgnu) to our compile time flags, which will make Clang warn whenever it encounters GNU extensions.
This would close#14130.
Also related to #17230, where it's suggested we use a GNU extension, the `gnu::pure` attribute.

1bdbbbdc46c4e50bf07bc362e7e391ea1a53ea2f build: suppress array-bounds errors in libxkbcommon (fanquake)
Pull request description:
2 changes to better support building with GCC 12, which out of the box, is currently broken if you want to build using depends.
Prevent `-Warray-bounds` errors when building libxkbcommon. i.e:
```bash
src/xkbcomp/ast-build.c:82:27: error: array subscript 'ExprDef[0]' is partly outside array bounds of 'unsigned char[32]' [-Werror=array-bounds]
82 | expr->expr.value_type = type;
| ~~~~~~~~~~~~~~~~~~~~~~^~~~~~
src/xkbcomp/ast-build.c:75:21: note: object of size 32 allocated by 'malloc'
75 | ExprDef *expr = malloc(size);
| ^~~~~~~~~~~~
```
It might be the case that these would be fixed by updating the
package, but that would also require installing new build tools (meson),
as well as potentially more dependencies (wayland), and it'd need
testing with Qt. For now, just turn the errors into wanrings.
Define `BOOST_NO_CXX98_FUNCTION_BASE` to prevent GCC warning about the use of `std::unary_function`. i.e:
```bash
/bitcoin/depends/aarch64-unknown-linux-gnu/include/boost/container_hash/hash.hpp:131:33:
warning: 'template<class _Arg, class _Result> struct std::unary_function' is deprecated [-Wdeprecated-declarations]
131 | struct hash_base : std::unary_function<T, std::size_t> {};
| ^~~~~~~~~~~~~~
In file included from /usr/include/c++/12/bits/unique_ptr.h:37,
from /usr/include/c++/12/memory:76,
from ./init.h:10,
from init.cpp:10:
/usr/include/c++/12/bits/stl_function.h:117:12: note: declared here
117 | struct unary_function
```
Boost `container_hash` (included via functional -> multi_index) uses
[`std::unary_function`, which was deprecated in C++11](https://en.cppreference.com/w/cpp/utility/functional/unary_function), and "removed" in
C++17. It's use causes warnings with newer compilers, i.e GCC 12.1.
Use the MACRO outlined in https://github.com/boostorg/container_hash/issues/22, and added to Boost Config for GCC 12 in https://github.com/boostorg/config/pull/430, to prevent it's use.
[BOOST_NO_CXX98_FUNCTION_BASE](https://www.boost.org/doc/libs/master/libs/config/doc/html/boost_config/boost_macro_reference.html):
> The standard library no longer supports std::unary_function and std::binary_function.
> They were deprecated in C++11 and is removed from C++14.

2525c096b002a89d4c561e1474800496ad8ebd7e build: remove configure checks for win libraries we don't link against (fanquake)
Pull request description:
While cross compiling, `HOST=x86_64-w64-mingw32`, none of these libs actually seem to be passed to the linker. i.e tailing a build with `make -j5 V=1 | rg -i 'mingwthrd|winspool|rpcrt4|crypt32'`.
I'm not 100% sure about `crypt32`, even though the majority of our Windows cryptography usage, i.e [`CryptAcquireContextW`](https://docs.microsoft.com/en-us/windows/win32/api/wincrypt/nf-wincrypt-cryptacquirecontextw) or [`CryptGenRandom`](https://docs.microsoft.com/en-us/windows/win32/api/wincrypt/nf-wincrypt-cryptgenrandom) is provided by `advapi32`.
Note that `rpcrt4` and `mingwthrd` are already missing from the MSVC build, so we can sync the remainder once it's clear what's actually needed. Hopefully sipsorcery can add some MSVC insight.

Backport of #23314
These tests are failing when run against OpenSSL 3, and have been

disabled them for now to avoid `make check` failures.
Note that this will also remove warning output from our build, due to
the use of deprecated OpenSSL API functions. See #23048.

e9189a750b237eba1befc6b16c12c2cee3e0176c build: more robustly check for fcf-protection support (fanquake)
Pull request description:
When using Clang 7, we may end up trying to use the flag when it won't
work properly, which can lead to confusing errors. i.e:
```bash
/usr/bin/ld: error: ... <corrupt x86 feature size: 0x8>
```
Use `AX_CHECK_LINK_FLAG` & `--fatal-warnings` to ensure we wont use the flag in this case.
We do this as even when the error is emitted, compilation succeeds, and the binaries produced will run. This means we can't just check if the compiler accepts the flag, or if compilation succeeds (without or without `-Werror`, and/or passing `-Wl,--fatal-warnings`, which may not be passed through to the linker).
This was reported by someone configuring for fuzzing, on Debian 10, where Clang 7 is the default.
See here for a minimal example of the problematic behaviour:

076183b36b76a11438463883ff916f17aef9e001 build: add -fcf-protection=full to hardening options (fanquake)
Pull request description:
Beginning with Ubuntu `19.10`, it's packaged GCC now has some additional hardening options enabled by default (in addition to existing defaults like `-fstack-protector-strong` and reducing the minimum ssp buffer size). The new additions are`-fcf-protection=full` and `-fstack-clash-protection`.
> -fcf-protection=[full|branch|return|none]
> Enable code instrumentation of control-flow transfers to increase program security by checking that target addresses of control-flow transfer instructions (such as indirect function call, function return, indirect jump) are valid. This prevents diverting the flow of control to an unexpected target. This is intended to protect against such threats as Return-oriented Programming (ROP), and similarly call/jmp-oriented programming (COP/JOP).
> -fstack-clash-protection
> Generate code to prevent stack clash style attacks. When this option is enabled, the compiler will only allocate one page of stack space at a time and each page is accessed immediately after allocation. Thus, it prevents allocations from jumping over any stack guard page provided by the operating system.
If your interested you can grab `gcc-9_9.3.0-10ubuntu2.debian.tar.xz` from https://packages.ubuntu.com/focal/g++-9. The relevant changes are part of the `gcc-distro-specs` patches, along with the relevant additions to the gcc manages:
> NOTE: In Ubuntu 19.10 and later versions, -fcf-protection is enabled by default for C, C++, ObjC, ObjC++, if none of -fno-cf-protection nor -fcf-protection=* are found.
> NOTE: In Ubuntu 19.10 and later versions, -fstack-clash-protection is enabled by default for C, C++, ObjC, ObjC++, unless -fno-stack-clash-protection is found.
So, if you're C++ using GCC on Ubuntu 19.10 or later, these options will be active unless you explicitly opt out. This can be observed with a small test:
```c++
int main() { return 0; }
```
```bash
g++ --version
g++ (Ubuntu 9.3.0-10ubuntu2) 9.3.0

113b: 00 00 00
113e: 66 90 xchg %ax,%ax
```
Note the insertion of an `endbr64` instruction when compiling and _not_ opting out. This instruction is part of the Intel Control-flow Enforcement Technology [spec](https://software.intel.com/sites/default/files/managed/4d/2a/control-flow-enforcement-technology-preview.pdf), which the GCC control flow implementation is based on.
If we're still doing gitian builds for the `0.21.0` and `0.22.0` releases, we'd likely update the gitian image to Ubuntu Focal, which would mean that the GCC used for gitian builds would also be using these options by default. So we should decide whether we want to explicitly turn these options on as part of our hardening options (although not just for this reason), or, we should be opting-out.
GCC has supported both options since 8.0.0. Clang has supported `-fcf-protection` from 7.0.0 and will support `-fstack-clash-protection` in it's upcoming [11.0.0 release](https://clang.llvm.org/docs/ReleaseNotes.html#id6).

8578c6fccd11404412d2c60f9bede311b79ca0d0 build: Fix search for brew-installed BDB 4 on OS X (Glenn Willen)
Pull request description:
~~NOTE: This PR contains one important fix that I need (to make Bitcoin Core build cleanly on my system without shenanigans), plus some related general cleanup that is not really necessary, and could be annoying. (I am prepared to defend my argument that BDB_CFLAGS is wrong here, and BDB_CPPFLAGS is right, but this could bite anybody who has gotten in the habit of -- or scripted -- setting the former.)~~
Ok, I have been convinced that I was too clever with the refactor and I have removed it. Now it's just the tiny change to fix the build on my local machine.
---
On OS X, when searching Homebrew keg-only packages for BDB 4.8, if we find it,
use BDB_CPPFLAGS and BDB_LIBS instead of CFLAGS and LIBS for the result. This
is (1) more correct, and (2) necessary in order to give this location
priority over other directories in the include search path, which may include
system include directories with other versions of BDB.

20a30922fbf6ba14e250ca649239af115dbbe7b0 doc: note why we can't use thread_local with glibc back compat (fanquake)
Pull request description:
Given that we went through a [gitian build](https://github.com/bitcoin/bitcoin/pull/18681) to remember why this is the case, we might as well make a note of it in configure.ac.
[From #18681](https://github.com/bitcoin/bitcoin/pull/18681#issuecomment-615526634):
Looking at the Linux build log, this has failed with:
```bash

```
`__cxa_thread_atexit_impl` is used for [thread_local variable destruction](https://sourceware.org/glibc/wiki/Destructor%20support%20for%20thread_local%20variables):
> To implement this support, glibc defines __cxa_thread_atexit_impl exclusively for use by libstdc++ (which has the __cxa_thread_atexit to wrap around it), that registers destructors for thread_local variables in a list. Upon thread or process exit, the destructors are called in reverse order in which they were added.
As suggested, this only became available in glibc 2.18. From the [2.18 release notes](https://sourceware.org/legacy-ml/libc-alpha/2013-08/msg00160.html):
> * Add support for calling C++11 thread_local object destructors on thread
and program exit. This needs compiler support for offloading C++11
destructor calls to glibc.

Pull request description:
Use `dnl` for all comments, rather than `#`.
Remove backticks - Their usage for the `bdb_prefix` and `qt5_prefix` commands may have improved backwards compatibility in some cases, however we now require recent versions of macOS. I'm not sure why they were being used in the `HAVE_STD__SYSTEM` and `HAVE_WSYSTEM` defines.

8f7b93047581c67f2133cdb8c7845471de66c30f Drop the leading 0 from the version number (Andrew Chow)
Pull request description:
Removes the leading 0 from the version number. The minor version, which we had been using as the major version, is now the major version. The revision, which we had been using as the minor version, is now the minor version. The revision number is dropped. The build number is promoted to being part of the version number. This also avoids issues where it was accidentally not included in the version number.
The CLIENT_VERSION remains the same format as previous as previously, as the Major version was 0 so it never actually got included in it.
The user agent string formatter is updated to follow this new versioning.
***
Honestly I'm just tired of all of the people asking for "1.0" that maybe this'll shut them up. Skip the whole 1.0 thing and go straight to version 22.0!
Also, this means that the terminology we commonly use lines up with how the variables are named. So major versions are actually bumping the major version number, etc.

e90e3e684ffa7b25f0dfb5b45e70bb0c358261fb build: fix sysctl() detection on macOS (fanquake)
Pull request description:
[`sysctl()` on *BSD](https://www.unix.com/man-page/FreeBSD/3/sysctl/) takes a "const int *name", whereas [`sysctl()` on macOS](https://developer.apple.com/library/archive/documentation/System/Conceptual/ManPages_iPhoneOS/man3/sysctl.3.html)
it takes an "int *name". So our configure check and `sysctl()` detection on
macOS currently fails:
```bash
/usr/include/sys/sysctl.h:759:9: note: candidate function not viable:
no known conversion from 'const int [2]' to 'int *' for 1st argument
int sysctl(int *, u_int, void *, size_t *, void *, size_t);
```
The simplest change seems to be to change the param to a "int *name", which
will work during configure on macOS and *BSD systems.
For consistency I've changed both calls, but note that macOS doesn't
have `KERN_ARND`, so that check will always fail regardless. We can revert/add
documentation if preferred.

f2747d1602ec4e1128356b861b2167daf66a845b build: Restrict check for CRC32C intrinsic to aarch64 (W. J. van der Laan)
Pull request description:
`crc32c`'s hardware accelerated code doesn't handle ARM 32-bit at all, but only 64-bit. Make the check in `configure.ac` check for this architecture explicitly. This change does not affect non-ARM architectures.
For the release binaries, the current `configure.ac` check happens to work: it enables it on aarch64 but disables it for armhf. However some combination of compiler version and settings can cause this check to succeed on armhf (as reported on IRC). So make the 64-bit platform requirement explicit.
(details: while the check already explicitly checks the `__crc32d` intrinsic, which strictly doesn't exist on 32-bit ARM, this is not enough! gcc happens to helpfully emulate it:
> These built-in intrinsics for the ARMv8-A CRC32 extension are available when the -march=armv8-a+crc switch is used "uint32_t __crc32d (uint32_t, uint64_t)" Form of expected instruction(s): Two crc32w r0, r0, r0 instructions for AArch32

This has been around since the introduction of autotools. However at
this point I'm not sure we'd ever want to suppress all warnings when
performing a build, and given that CXX FLAGS will have been overriden
when cross-compiling for Windows (using depends), this would rarely,
if-ever be used anyways.

Pull request description:
Adds an offline tool `bitcoin-wallet-tool` for wallet creation and maintenance.
Currently this tool can create a new wallet file, display information on an existing wallet, and run the salvage and zapwallettxes maintenance tasks on an existing wallet. It can later be extended to support other common wallet maintenance tasks.
Doing wallet maintenance tasks in an offline tool makes much more sense (and is potentially safer) than having to spin up a full node.

* Merge #18750: build: optionally skip external warnings
ba8950ee0134a7958e3e9b041cd54d222feb09a1 build: optionally skip external warnings (Vasil Dimov)
Pull request description:
Add an option to `./configure` to suppress compilation warnings from
external headers. The option is off by default (no change in behavior,
show warnings from external headers).
This option is useful if e.g. Boost or Qt is installed outside of
`/usr/include` (warnings from headers in `/usr/include` are already
suppressed by default) and those warnings stand in the way of compiling
Bitcoin Core with `-Werror[=...]` or they just clutter the build output
too much and make our own warnings hard to spot.
`-isystem /usr/include` bricks GCC's `#include_next`, so we use
`-idirafter` instead. This way we don't have to treat `/usr/include`
specially.

399d84da3708719b063953107bab0f5f6493addb build: Only allow ASCII identifiers (Wladimir J. van der Laan)
Pull request description:
While emoji and other symbols in C++ identifers (as accepted by newer compilers) are fun, they might create confusion during code review, for example because some symbols look very similar. Forbid such extended identifiers for now.
This is done by providing `-fno-extended-identifiers`. Thanks to sipa for suggesting this compiler flag.

e8a8cff07c409c7eecd478d3df36c7ba92c59730 build: enforce minimum required Windows version (7) (fanquake)
Pull request description:
Instruct the linker to set the major & minor subsystem versions in the PE
header to 6 & 1 (NT 6.1 which corresponds to Windows 7). Similar to
the behaviour on macOS, the binary will now refuse to run on
unsupported versions of Windows, which, for us, is XP & Vista.

1a011b3a8285a21ca9618a35bb841d3f2d48b247 build: remove -Wdeprecated-register from NOWARN flags (fanquake)
Pull request description:
The `register` keyword was deprecated in C++11, and [removed in C++17](https://en.cppreference.com/w/cpp/keyword/register). Now that we require C++17, we shouldn't have to suppress warnings for a non-existent feature.

cd24f37ea9168bd56b8c518ea6125e242cc4213d doc: Better explain GNU ld's dislike of ld64's options (fanquake)
Pull request description:
There's also now more than a single option being special cased for
darwin. If we didn't special case these options they would still end
up on the link line and the binaries produced would just segfault.
I'm going to plug #17874 here as well, because adding
`-fatal-warnings` to our `AX_CHECK_LINK_FLAG` calls would
mostly prevent this sort of option mangling from happening.
An example of the warning behaviour:
```bash
echo "int main() {}" | g++ -x c++ -std=c++11 -Wl,-dead_strip -
/usr/bin/ld: warning: cannot find entry symbol ad_strip; defaulting to 0000000000001040
nm -C a.out
0000000000001000 t _init
0000000000001040 T _start
U ad_strip
```
