I was indeed confused. However, it seems that ATLAS doesn't build on
MIPS either, based on its 'supported-systems' field.
So, I come again to the same conclusion: that we should switch to
OpenBLAS on _all_ platforms, and strip away the ATLAS-handling code in
our python-numpy package. We can work on fixing OpenBLAS to MIPS later.
What do you think?
Thanks!
