config/x86: fix MinGW cross build with Meson 0.49
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:
In file included from /usr/lib/gcc/x86_64-w64-mingw32/9.3-win32/include/immintrin.h:55,
from /usr/lib/gcc/x86_64-w64-mingw32/9.3-win32/include/x86intrin.h:32,
from ../dpdk/lib/net/net_crc_avx512.c:13:
/usr/lib/gcc/x86_64-w64-mingw32/9.3-win32/include/avx512fintrin.h:1650:1:
error: inlining failed in call to always_inline _mm512_ternarylogic_epi64:
target specific option mismatch
1650 | _mm512_ternarylogic_epi64 (__m512i __A, __m512i __B, __m512i __C,

../dpdk/lib/net/net_crc_avx512.c:59:9: note: called from here
59 | return _mm512_ternarylogic_epi64(tmp0, tmp1, data_block, 0x96);
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
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.

devtools: add Windows cross-build test with MinGW
The Meson cross file is renamed from meson_mingw.txt to cross-mingw,
and is added to test-meson-builds.sh.
The only example supported on Windows so far is "helloworld",
that's why the default list of examples is overridden.
