Cross build with MinGW was broken for the baseline meson 0.49.2.
Cause: in c_args = '-mno-avx512f' from config/x86/cross-mingw,
each character was treated as a separate compiler option:
meson.build:4:0: ERROR: Compiler x86_64-w64-mingw32-gcc can not compile programs.
With c_args = ['-mno-avx512f'] configuration passed, but build failed,
because Meson placed -mno-avx512f after -mavx512f in CFLAGS:

Additionally, -m[no-]avx512f flag is expected to be in machine_args
by all the checks in meson.build files.
Commit 419c6e9af69e ("net/i40e: fix build for Windows MinGW")
fixed the errors cause by MinGW using AVX512F on Windows.
The binutils AVX512F bug check is now portable,
so enable it for Windows to switch AVX512 support on and off
without any special logic for MinGW.
Fixes: 549bfc83168f ("config: disable AVX512 with MinGW")
