    Description

      QTBase (at least 6.5.1 but possibly other versions as well) fails to compile on certain processors models with errors related to AVX.  For instance, on an Intel i7-12800H, there are errors suggesting to "... enable all x86-64-v3 extensions".  I have attached a build log from my Gentoo environment.

      This problem seems similar to and may be related to a bug that I found with QTGUI where I had to disable AVX2 (by passing -mno-avx2 to my CFLAGS) or else the resulting binaries would segfault.
