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.

54c7754f31 build: use aarch64 Clang if cross-compiling for darwin on aarch64 (fanquake)
Pull request description:
If we're cross-compiling for darwin on aarch64 hardware, we need to
use a Clang that will run on that hardware.
Only tested in a Linux Docker container (aarch64-unknown-linux-gnu),
running on an Apple M1 mac-mini (aarch64-apple-darwin20.5.0).

ACK 54c7754f31, I agree it can be merged (fix in #22448 is orthogonal to this one).

a58868d201 build: Makes rcc output always deterministic (Hennadii Stepanov)
Pull request description:
The Qt Resource Compiler ([rcc](https://doc.qt.io/qt-5/rcc.html)) has a command-line option `--format-version` which has the [default value](https://code.qt.io/cgit/qt/qtbase.git/tree/src/tools/rcc/main.cpp?h=5.12.10#n172) 2.
The only difference from `--format-version 1` is adding a [last modified timestamp](https://code.qt.io/cgit/qt/qtbase.git/tree/src/tools/rcc/rcc.cpp?h=5.12.10#n207) to the output file ([credits](https://github.com/bitcoin/bitcoin/pull/21654#issuecomment-819198228) to **fanquake**). That, in turn, forces us to use `QT_RCC_SOURCE_DATE_OVERRIDE=1` to get deterministic builds (#13732).
This change makes rcc output always deterministic by using `--format-version 1` option that makes usage of the
`QT_RCC_SOURCE_DATE_OVERRIDE` needless.

Also it improves interaction with ccache:
On master (f6c44e999b):

After two reports on IRC of issues building depends on an Apple M1
machine, it turns out that this option can't be used when targeting
arm-apple-darwin. For now, just use it for x86_64-apple-darwin.
