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.

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.

We need to append-to rather than set CXXFLAGS, otherwise we loose -O2 &
-pipe. Currently this results in zeromq being built without optimizations
at all (or whatever the compiler would default too, essentially always -O0).
Bdb is the same, for the CXX portion of its code. C code has been built
with -O2.
Boost has actually been uneffected because it receives -O3 from it's own
build flags.

42b589d18f scripts: test for MACHO control flow instrumentation (fanquake)
469a5bc4fa build: build Boost with -fcf-protection when targeting Darwin (fanquake)
Pull request description:
Addresses the macOS portion of #21888.
Build Boost with `-fcf-protection` when targeting Darwin. This should be ok, because our cross-compiler (Clang 10) supports the option, and I'd expect all versions of Apple Clang being used to compile Core would also support it. Building Boost with this option is required so that the `main` provided to `test_bitcoin` has instrumentation.
Note that the presence of instrumentation does not mean it will be used, as that is determined at runtime by the CPU.
From the Intel control flow enforcement documentation:
> The ENDBR32 and ENDBR64 instructions will have the same effect as the NOP instruction on Intel 64 processors that do not support CET. On processors supporting CET, these instructions do not change register or flag state. This allows CET instrumented programs to execute on processors that do not support CET. Even when CET is supported and enabled, these NOP–like instructions do not affect the execution state of the program, do not cause any additional register pressure, and are minimally intrusive from power and performance perspectives.
Follow up from #21135.

Closes: #21242

Reproduced from depends/Makefile comment:
When invoking a shell, GNU Make special-cases exit code 127 (command not
found) by not capturing the output but instead passing it through. This
is not done for any other exit code.
Therefore, we require a "|| true" to avoid this behaviour when in an
environment where the build_* or host_* may not exist yet.

a5491882a0 build: fix configuring when building depends with NO_BDB=1 (fanquake)
Pull request description:
Currently, if you build depends using `NO_BDB=1` (only sqlite wallets), `./configure` will fail as it still tries to find bdb. i.e:
```bash

...

This PR fixes the build such that you can build depends, opting out of bdb, without opting out of wallets entirely, and still configure successfully. I think I've tested across most potential configurations. i.e:
```bash

bdb & sqlite are both are available
./configure --without-bdb (bdb and sqlite on system)
only sqlite
./configure --without-sqlite (bdb and sqlite on system)

./configure --disable-wallet (bdb and sqlite on system)

cf971c9ea0 build: use -isysroot over --sysroot on macOS (fanquake)
Pull request description:
Not only does this seem to be the more correct behaviour when targeting Darwin, but if you use `-isysroot`, Clangs Darwin driver will [infer the deployment target](3e037f8f0e/clang/lib/Driver/ToolChains/Darwin.cpp (L1652)) from the SDK and use other SDK info when parsing arguments to the linker. In the case of [`-platform_version`](3e037f8f0e/clang/lib/Driver/ToolChains/Darwin.cpp (L2656)), which is added if the linker is [new enough](3e037f8f0e/clang/lib/Driver/ToolChains/Darwin.cpp (L342)), the version tuple is constructed from the SDKInfo, and SDKInfo, as far as I can tell, only exists when `-isysroot` has been passed, see [parseSDKSettings](3e037f8f0e/clang/lib/Driver/ToolChains/Darwin.cpp (L1785))
As a result, the SDK version field in the `LC_BUILD_VERSION` command is filled out. i.e when building master:
```bash
cmd LC_BUILD_VERSION
cmdsize 32
platform 1
minos 10.14
sdk n/a
ntools 1
tool 3
version 650.9
```
vs this PR:
```bash
cmd LC_BUILD_VERSION
cmdsize 32
platform 1
minos 10.14
sdk 11.3
ntools 1
tool 3
version 650.9
```
This, from what I understand, will fix the issue we are having with Qt deciding wether or not to enable features like "Dark mode" on macOS, see #21771, however I have not tested that. Thus this is an alternative to #21782.
Our usage of `--sysroot` was added in #17118.
```bash
-isysroot <dir> Set the system root directory (usually /)

Even though programs should never depend on a particular `QHash` ordering, there may be situations where you temporarily need deterministic behavior, for example for debugging or regression testing. To disable the randomization, define the environment variable `QT_HASH_SEED` to have the value 0.
Since #3620 we use `QT_RCC_TEST=1` to achieve a deterministic output.
Since Qt 5.3.1 hash seeding is disabled for all of the bootstrapped tools, including rcc. Therefore, `QT_RCC_TEST=1` is no longer needed.

We now use a script named gen_id to generate the base build_id/host_id.
This solves 2 problems:
1. GNU Make special-casing exit code 127 (command not found) meant that
warnings about missing tools would propagate to the user's terminal
and broke our opportunistic build_id construction.
2. This change ensures that we don't have arbitrary characters in our
make variables that would be misinterpreted by Make.
See comments in depends/Makefile and depends/gen_id for more
information.
