>Description:
Mozilla products don't compiled with -march=native

I have -march=native in my CFLAGS in /etc/mk.conf. Mozilla products don't compile now.

mail/thunderbird:

/usr/include/gcc-10/avx2intrin.h: In function '__m256i mozilla::CmpEq256(__m256i, __m256i) [with TValue = unsigned char]':

  231 | _mm256_cmpeq_epi8 (__m256i __A, __m256i __B)

   52 |     return _mm256_cmpeq_epi8(a, b);
      |            



www/firefox115:

/usr/include/gcc-10/avx2intrin.h:231:1: error: inlining failed in call to 'always_inline' '__m256i _mm256_cmpeq_epi8(__m256i, __m256i)': target specific option mismatch

      |            ~~~~~~~~~~~~~~~~~^~~~~~

>How-To-Repeat:
Add -march=native to CFLAGS in /etc/mk.conf and build firefox115 or thunderbird.

I've seen this issue on now older firefox and thunderbird pkgsrc versions over the last couple of years as well.
>Fix:
The most straight-foward way is probably to remove -march=native from BUILDLINK_TRANSFORM:
