commit: https://git.buildroot.net/buildroot/commit/?id=97651ce275198ed650da7944b967d93a79127bd9
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master
The westmere line of x86_64 targets lies between nehalem (corei7) and
sandybridge (corei7-avx). Allowing use of -march=westmere enables use of
AES instruction set on these targets.
