I agree.  We should provide binaries for OpenBLAS for non-Intel users.
Here’s the rules file used by the Debian packages:

    https://sources.debian.net/src/openblas/0.2.14-1/debian/rules/

DYNAMIC_ARCH is enabled for x86 archs; for other architectures they pass
the TARGET variable.  I have a patch for setting the TARGET for mips,
which I’m planning to test on a build slave by the end of this week.
