Subject: [PATCH] numpy: set lapack, blas sections
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When using netlib lapack/blas, the section name doesn’t match what
numpy expects. So we need to add extra sections for both so that the
right directory is found. The original “blas.implementation” section
may not actually be still required, but it is still a good idea so
that numpy know whether to apply any blas-implementation specific
quirks.

Fixes #86613
