We believe the reason being the fact that hydra doesn't handle the flag
'#:substitutable?' properly. As a result we have the following
situation:

1. hydra builds a version of ATLAS optimized for its CPU locally.

2. 'python-numpy-bootstrap' and co., on some architectures, probably get
an incompatible version of ATLAS and therefore fail to pass some tests.

You can check in the build log of 'python-numpy-bootstrap' that ATLAS,
despite the flas, is substituted (no local build on the slave).

At some point we should fix the support for '#:substitutable?' on hydra
(or the upcoming 'guix publish').
