sage: re-add pkg-config aliases

Those were removed because they were added to openblas itself. There was
an error with that however and it will take some time until the fix
makes its way through staging. For the time being, reverting this part
of 26d5d030fe498b64a307af35ff96ff215ccd967a will fix the sage build.
This commit should be reverted once
408eacbc896ecc6d0e25238963ecbd412d78ce3c is in master.
