Originally, numpy used the cblas from openblas, so this did not matter.

Only when numpy changed from openblas to netlib-lapack (@3.5.0), the missing
cblas became a problem.


For numpy + cblas, there are two options:

1. Build numpy as part of Backports, which already *has* cblas.
2. Bring an updated lapack (>= 3.6.0) to SLE. But as far as I understand, this
*also* goes into backports only, so we also need to build numpy in backports.
