Bug#905826: libjulia depends on libblas.so.3 instead of openblas?

[Milan Bouchet-Valat]

I second this (and I'm sure this reflects the opinion of upstream in
general). It's really important that after installing the julia package
one gets the same performance as with official upstream binaries. It's
a trap to use the Netlib reference BLAS/LAPACK by default, which is
known to be terribly slow and not even tested by upstream.
