 Trying to build OpenBLAS @0.3.12 +gcc9 on a MacPro 6.1 (macOS 10.14.6,
 Xcode 11.3.1) leads to errors in the build complaining that AVX features
 cannot be inlined into functions compiled without AVX support:

 Likewise for the attempted inlining of {{{_mm256_add_ps}}}.
 {{{_mm256_loadu_ps}}}, and so on.

 My machine only supports AVX1 according to {sysctl}.

 I haven't yet tried OpenBLAS-devel.

 Logfile attached.
