build/x86: fix support for old compilers
Some older compilers e.g. gcc 8.5, do not support overriding
-march=native with another architecture, leading to build warnings such
as reported in Bugzilla (link below). Add a check for that case, and
explicitly add the avx512 flags if necessary.
Note: it appears that it is only the "native" flag that isn't
overridden, which makes the issue hard to reproduce e.g. using
godbolt.org, or on a modern machine. For example, testing with gcc 8.5
on a haswell machine, using 'native' vs explicit 'haswell':
gcc -march=native -march=skylake-avx512 -dM -E - < /dev/null | grep AVX512 | wc -l
0
gcc -march=haswell -march=skylake-avx512 -dM -E - < /dev/null | grep AVX512 | wc -l

Bugzilla ID: 1736
Fixes: e361ae3f59d3 ("build: reduce use of AVX compiler flags")
