Solus currently builds everything with -mtune=generic -march=x86-64, which means in multiple cases where we'd really, really, like to, we can't leverage new CPU features.
By adopting the Clear Linux patch(s) we can supply avx2 variants of the libraries into /usr/lib64/avx2 and have glibc automatically load them instead.
This will enable us to attack performance-sensitive packages such as mesalib, providing avx2 versions of the libs that would put us at Haswell+
to leverage the modern features, all without breaking the main libraries for our existing users that do not have this hardware support.
