Since Qt 5.14.0 the CROSS_COMPILE variable always being overridden by
the Qt build system internally.

19f3896c9a build: Fix x86_64 <-> arm64 cross-compiling for macOS (Hennadii Stepanov)
Pull request description:
Currently, on master (111c3e06b3), dependencies are built for the build system architecture, not the provided host.
On Intel-based macOS Big Sur 11.6.1 (20G224):
```
% make -C depends HOST=arm64-apple-darwin20
% lipo -info depends/arm64-apple-darwin20/lib/libsqlite3.a
Non-fat file: depends/arm64-apple-darwin20/lib/libsqlite3.a is architecture: x86_64
```
On M1-based macOS Monterey 12.0.1 (21A559) the `boost` package building fails with multiple errors like that:
```
% make -C depends boost HOST=x86_64-apple-darwin19
...
error: option 'cf-protection=return' cannot be specified on this target
error: option 'cf-protection=branch' cannot be specified on this target
2 errors generated.
```
This PR allows to cross-compile as follows:
- on Intel-based macOS Big Sur 11.6.1 (20G224):
```
% make -C depends HOST=arm64-apple-darwin20
% lipo -info depends/arm64-apple-darwin20/lib/libsqlite3.a
Non-fat file: depends/arm64-apple-darwin20/lib/libsqlite3.a is architecture: arm64
% CONFIG_SITE=$PWD/depends/arm64-apple-darwin20/share/config.site ./configure
% make
% lipo -info src/qt/bitcoin-qt
Non-fat file: src/qt/bitcoin-qt is architecture: arm64
```
- on M1-based macOS Monterey 12.0.1 (21A559):
```
% make -C depends HOST=x86_64-apple-darwin19
% CONFIG_SITE=$PWD/depends/x86_64-apple-darwin19/share/config.site ./configure
% make
% lipo -info src/qt/bitcoin-qt
Non-fat file: src/qt/bitcoin-qt is architecture: x86_64
```
No behavior change for other builder-host pairs.
This is an alternative to bitcoin/bitcoin#22506.

ACK 19f3896c9a - this is definitely cleaner than the approach in #22506. I've tested the x86_64 -> arm64 and arm64 -> x86_64 cross-compiles. Going to go-ahead and merge this given it's scoped to building for darwin targets, on darwin. Not sure if this is something we'll actually see used very often.

6575d354c8 build: Bump Fonconfig version up to 2.12.6 (Hennadii Stepanov)
Pull request description:
This PR gets rid of `remove_char_width_usage.patch`.
Some additional observations:
1. Newer Fontconfig versions (2.13.0 and 2.13.1) introduce a new dependency, `uuid`, in the [`7b48fd3dd406b926f0e5240b211f72197ed538a9`](7b48fd3dd4) commit
2. In Fonconfig 2.13.1 (the current stable) excludes the `fcobjshash.h` from the distributive archive (see [`31269e3589e0e6432d12f55db316f4c720a090b5`](31269e3589)), that makes our `gperf_header_regen.patch` unusable, and requires `gperf` as a dependency.

ACK 6575d354c8 - from the best I can determine this doesn't have any versioning / ABI implications. The ABI difference between 2.12.1 and 2.12.6 is two symbol additions, neither of which are used by Qt. Fontconfig seems to be better at maintaining backwards compatibility compared to a library like Freetype.

2f356a0ca8 scripted-diff: Drop Darwin version for better maintainability (Hennadii Stepanov)
Pull request description:
After this PR, any macOS tools version bumping in the future will touch fewer files in the repo.
Pointing a Darwin version for the `--host` system does not matter for the following reasons:
- in terms of the resulted binaries, we should only care about the minimum supported macOS version which is a separated parameter in our build system.
- in terms of the build system itself, the usage of the `$(host)` variable is self-consistent enough. Btw `$(host_os)` value already has the version dropped:
```
$ make -C depends --no-print-directory print-host_os HOST=x86_64-apple-darwin19
host_os=darwin
```

Very old shells suffered from bugs which meant that prefixing variables
with an "x" to ensure that the lefthand side of a comparison always
started with an alphanumeric character was needed. Modern shells don't
suffer from this issue (i.e Bash was fixed in 1996).
In any case, we've already got unprefixed checks used in our codebase,
i.e https://github.com/bitcoin/bitcoin/blob/master/configure.ac#L292,
and have dependencies (in depends) that also use unprefixed comparisons.
I think it's time that we can consolidate on not using the x-prefix
workaround. At best it's mostly just confusing.

ac323a7222 build: Switch to llvm buinutils for Android builds (Hennadii Stepanov)
Pull request description:
The new Long Term Support release of the Android NDK is [available](https://groups.google.com/g/android-ndk-announce/c/MS6Qoub0DKE/m/Zfp5Ys8eAAAJ) since 2021-08-11:
> As r23 is the new LTS, the support windows for r21 and r22 have now ended.
On master (8ae4ba481c), dependency build fails because it expects GNU Binutils are present in the Android NDK. In [fact](https://android.googlesource.com/platform/ndk/+/master/docs/BuildSystemMaintainers.md#binutils):
> GNU Binutils remains available up to and including r22. All binutils tools with the exception of the assembler (GAS) were removed in r23. GAS was removed in r24.
This PR switches our depends build system to llvm binutils. The usage of `llvm-ar` and `llvm-ranlib` tools effectively makes r21 the minimum supported version of NDK.
With this PR:
- building depends against NDK r23 LTS now is possible with `NO_QT=1`
- building the `qt` package in depends against NDK r23 LTS still fails:
```
Creating qmake...
...
ERROR: Cannot detect Android NDK toolchain.
Please use -android-toolchain-version to specify it.
```
The issue with the `qt` package is going to be addressed in another PR.
