I'll send a PR. Got it, thanks for your help. I'll also send a PR to
repository, so that it's clear how to actually use it with NumPy.

Absolutely, I don't plan to use nor ship openblase. My apologies
for the confusion. I was just using it on linux to understand how to
make numpy use it (with the ATLAS, BLAS and LAPACK env variables).
