description:
math/py-numpy: Actually use BLAS_LIBS and LAPACK_LIBS.

The previous state included our BLAS choice but the build
did not honour the selected libs. This patches the config
script to not search for LAPACK and BLAS, using our settings
instead. Hopefull we can get that option upstreamed.

Approved during freeze by wiz.

 Disable openblas detection.  In pkgsrc, use mk/blas.buildlink.mk.
