Here is a diff for numpy that backports patches to enable CPU feature

PLEASE, Brad, tell us what you tested and what you didn't test when
you propose patches, especially arch-dependent ones.
This still builds on riscv64.
It shouldn't matter much, but I'd prefer that you initialize 'hwcap'
to zero and/or add error checking around elf_aux_info().
I have build tested and ran 'make test' on both arm64 and riscv64.
Nothing changes about riscv64.

I'll see about zero initializing hwcap.
