BUG: ensured that warnings/errors are raised when nothing is requested

When a user requests NPY_BLAS/LAPACK_ORDER they can omit Netlib
BLAS/LAPACK. In that case there will not be raised anything.
This commit fixes this issue so that there will always be
issues raised if the user hasn't requested the basic libraries.
