intel-mkl does not set alternatives for non-multiarch blas/lapack in Stretch

[Frederik Himpe <fhimpe@ai.vub.ac.be>]

The intel-mkl backport sets multiarch alternatives for libblas and
liblapack. However Stretch does not use multiarch libblas/liblapack
yet, which means that all Stretch packages still are not using libmkl,
even when set as default.
