Accepting request 839831 from home:StefanBruens:branches:devel:languages:python:numeric

- Add cblas build dependency, otherwise numpy uses naive internal
  implementations for some blas operations, mitigates boo#1177260.
- Add libopenblas recommends. To actually use openblas instead of
  netlib BLAS/LAPACK, update-alternatives has to be used.
- Remove .pytest_cache from the build_root
