bcff8e21b1bb360c3cf1e1d2e1a2a54ec7581720 build: only pass --disable-dependency-tracking to packages that understand it (fanquake)
Pull request description:
By blanket passing `--disable-dependency-tracking` to all depends packages we end up with warnings (i.e in `bdb` or `freetype`) like:
```bash
configure: WARNING: unrecognized options: --disable-dependency-tracking
```
Instead, only pass it to packages that actually understand it. Related to https://github.com/bitcoin/bitcoin/issues/16354.
More info on `--disable-dependency-tracking` available [here](https://www.gnu.org/software/automake/manual/html_node/Dependency-Tracking.html).
This PR also adds `--enable-option-checking` as a configure option to all applicable packages.

Even if we potentially check the integrity of the downloaded file via hash comparison, we should make use of SSL since it is available.

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:
```bash
configure:18704: checking for mutexes
configure:18815: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang -mmacosx-version-min=10.12 --sysroot /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk -o conftest -pipe -O2 -I/Users/michael/github/fanquake-bitcoin/depends/x86_64-apple-darwin19.6.0/include -L/Users/michael/github/fanquake-bitcoin/depends/x86_64-apple-darwin19.6.0/lib conftest.c -lpthread >&5

```
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.
Fixes#19411.

* build: Enable C++11 build, require C++11 compiler
Implements #6211.
* depends: use c++11
* build: update ax_cxx_compile_stdcxx to serial 4
* build: force a c++ standard to be specified
Newer compilers may switch to newer standards by default. For example, gcc6
uses std=gnu++14 by default.
* c++11: fix libbdb build against libc++ in c++11 mode
atomic_init clashes with
* c++11: CAccountingEntry must be defined before use in a list
c++11ism. This fixes builds against libc++.
