[oe] [PATCH] Don't use host version of libblas and liblapack for python-numpy

[Laurent Pinchart]

When trying to locate libblas and liblapack, numpy will use the host
versions of those libraries if available. This breaks compilation when
linking.

Fix the problem by disabling libblas and liblapack support completely,
as OpenEmbedded doesn't provide recipes for those libraries anyway.
