dev-util/mingw64-runtime: pass -mno-avx for mingw cross
AVX issues with mingw-gcc aren't exactly new, e.g.
https://bugs.winehq.org/show_bug.cgi?id=45289
Been known to cause issues with dxvk too, albeit unsure
if that's still relevant as issues are scattered/lost.
Newly, >=wine-8.10 is likely to crash doing anything
at all 32bit if used -march=native (w/ avx) and 32bit
(e.g. `WINEARCH=win32 winecfg`).
Adding this to every packages using mingw as a precaution,
not believed there is much to gain from keeping AVX given
the fragility here. May revisit eventually with a newer GCC.
Not known to have caused issues with this package in particular
(unlike wine/dxvk), so skipping a slow rebuild revbump.
Unlike other ebuilds, also bother doing tc-is-gcc given what's
used is more up in the air for this ebuild.
