I just spent some time working on getting it to build natively on a Pi3
successfully (failed about 85 for 3500 tests). Next step is see if I can
use the same trick numpy does to get a configuration in place so it
cross compiles.

The configure phase of the compile is completely broken for cross
compilation since it is collecting information about python from the
sysroot, which is not going to match python on the target.

I skipped atlas and built lapack. Atlas has similar issues with cross
compilation.

I'm coming back to this, but not for several weeks.
