[PATCH v2 00/13] Add aarch64-w64-mingw32 target

[Radek Barton]

Hello, everyone.

Currently, we are able to provide results of regression testing for `x86_64-w64-mingw32` target with `--enable-languages=c,lto,c++,fortran` running in WSL only.

The summarized results, both for the branch with patch set applied and its corresponding base branch, show:

517501 expected passes
4537 of expected failures
10828 unexpected failures
180 of unexpected successes
5934 of unresolved testcases
19113 of unsupported tests

which means that 98% of the tests ends in an expected way and we haven't detected a single regression between the branches.

The detailed results can be downloaded and reviewed at https://github.com/Windows-on-ARM-Experiments/mingw-woarm64-build/actions/runs/8327889403

Best regards,
