181989f6c9427fc266dbdcc84cb60ac03e67cdb2 build: Add variable printing target to Makefiles (Carl Dong)
Pull request description:

I kept finding myself needing these to debug our build system, since
they are innocuous and are very helpful they probably belong in the
codebase.

Pull request description:
Related to #16354.
This PR adds additional configure flags to packages in depends to explicitly disable features we aren't using; similar to #16183. It also fixes passing `--without-tools` to `qrencode`.
I've added `--disable-drafts` to `zeromq`:
```bash
Build and install draft classes and methods [default=yes]
```
I'm not entirely sure how far we want to take this. i.e in the `zeromq` package we explicitly pass `--without-libsodium`, even though it's disabled by default.
Do we also want to explicitly pass all the other `--without` flags? :
```bash
--with-libgssapi_krb5 require libzmq build with libgssapi_krb5
[default=no]
--with-libsodium use libsodium instead of built-in tweetnacl
[default=no]
--with-pgm build libzmq with PGM extension. Requires pkg-config
[default=no]
--with-norm build libzmq with NORM protocol extension,
optionally specifying norm path [default=no]
--with-vmci build libzmq with VMCI transport [default=no]
```

Seems like older versions of macOS pretend to support c++17 std libs but do not have/have issues with uncaught_exceptions. "Catch", the testing framework used in the bls lib wants those by default but setting `DCATCH_CONFIG_NO_CPP17_UNCAUGHT_EXCEPTIONS` disables them which should be just fine to do in all cases here.

Pull request description:
Related to: #16150
We noticed that we could build QT without using XLib/libX11 as a library. XLib/libX11's headers are still used, and a minimal `configure.ac` has been added to eliminate overly-enthusiastic configure-time dependencies that aren't actually required to obtain the headers.
This also means that we eliminate XLib/libX11 as required shared libraries at runtime, which is desirable.
See commit messages for more details.
---
Reviewers: I am least sure about the minimal `configure.ac`, as I'm not too familiar with the autoconf syntax. Any improvements w/re robustness would be welcome.

Pull request description:
This PR makes `bitcoin_qt.m4` to use `pkg-config` for all hosts and removes non-pkg-config paths from it. This is a step towards the idea which was clear [stated](https://github.com/bitcoin/bitcoin/pull/8314#issue-76644643) by Cory Fields:
> I believe the consensus is to treat Windows like the others and require pkg-config across the board. We can drop all of the non-pkg-config paths, and simply AC_REQUIRE(PKG_PROG_PKG_CONFIG)
There are two unsolved problems with this PR. If depends is built with `DEBUG=1` the `configure` script fails to pickup Qt:
- for macOS host (similar to, but not the same as #16391)
- for Windows host (regression)
The fix is ~on its way~ submitted in #18298 (as a followup).
Also this PR picks some small improvements from #17820.

d0a829e9632379e42f0be5c554e3b692f0d14a95 build: fix mutex detection when building bdb on macOS (fanquake)
Pull request description:
Starting with the Apple Clang shipped with Xcode 12, [Apple has enabled -Werror=implicit-function-declaration by default](https://developer.apple.com/documentation/xcode-release-notes/xcode-12-release-notes):
> Clang now reports an error when you use a function without an explicit declaration when building C or Objective-C code for macOS (-Werror=implicit-function-declaration flag is on). This additional error detection unifies Clang’s behavior for iOS/tvOS and macOS 64-bit targets for this diagnostic. (49917738)
This causes bdbs mutex detection to fail when building on macOS (not cross-compiling):
```bash
checking for mutexes... UNIX/fcntl
configure: WARNING: NO SHARED LATCH IMPLEMENTATION FOUND FOR THIS PLATFORM.
configure: error: Unable to find a mutex implementation
```
as previously emitted warnings are being turned into errors. i.e:

```
Append `-Wno-error=implicit-function-declaration` to `cflags` so that `-Wimplicit-function-declaration` [returns to being a warning](https://clang.llvm.org/docs/UsersManual.html#cmdoption-wno-error), and the configure checks succeed.

50037e97d11356218c4b36767232e47b74742b0b depends: fix boost mac cross build with clang 9+ (Cory Fields)
Pull request description:
The ancient "darwin-4.9.1" profile has long been used to match against clang, which prior to version 9, reported 4.9.1 as its version when invoking "clang++ -dumpversion". Presumably this was a historical compatibility quirk related to Apple's switch from gcc to clang.
This was "fixed" in clang 9.0, so that -dumpversion reports the real version. Unfortunately that had the side-effect of breaking the (brittle) boost compiler detection.
Move to the seemingly more-correct "clang-darwin" profile, which passes the checks and builds correctly.
Also switch to using ar rather than libtool for archiving, as it's what the clang-darwin profile expects to be using.
Note that because this is using a different profile, some of the final command-line arguments end up changing. Those changes look sane at a glance.

Pull request description:
Fixes#14339. Thanks to @fanquake for confirming.
A few years ago, libfreetype introduced ```FT_Get_Font_Format()``` as an alias for ```FT_Get_X11_Font_Format()```, but ```FT_Get_X11_Font_Format()``` was kept for abi backwards-compatibility.
Our qt bump to 5.9 introduced a call to```FT_Get_Font_Format()```. Replace it with ```FT_Get_X11_Font_Format()``` in order to remain compatibile with older freetype, which is still used by e.g. Ubuntu Trusty.
Needs 0.17 backport.

This workaround should no longer be required, as it should have only been in use when compiled with the 10.7 SDK, which we haven't been building with for a while now.
5bc5ae30982a0f0f6a9804b05d99434af770c724
The bugreport linked with this code is for an unrelated? issue, however from what I can tell the correct QTBUG is this one https://bugreports.qt.io/browse/QTBUG-20880. Reading though the discussion there, it seems that the way progress bars are animated changed in macOS 10.10.
Qt was patched [here (5.5+)](https://codereview.qt-project.org/#/c/112379/):
> Disable progress bar animations on 10.10 Yosemite and higher - the native style does not animate them any more. Keep the indeterminate progress bar animation.
Given all of that, I don't think this is worth keeping around, as it would seem to only be useful in the case that a macOS user is compiling with a Qt < 5.5. That should be pretty unlikely, as we don't support downloaded Qt binaries, and brew currently provides [5.11.1](571b46213c/Formula/qt.rb).

00db418176 Add aarch64 qt depends support for cross compiling bitcoin-qt (TheCharlatan)
Pull request description:
This also adds a generic qt linux target in packages.mk . I am a bit confused by the existing docs for the RISC addition. Are there boards that would support running bitcoin-qt, or at the very least forwarding X over ssh? Is everybody building depends with `NO_QT=1` when targeting RISC? If not, I will revert the change for a generic qt linux package definition back to the piecemeal solution.
This pull request should close#13495
