Description:

Lapack 3.4.0 has a bug with rather severe consequences for octave, one of which is that matrix 2-norms of fat matrices cannot be computed. I updated the blas and lapack packages to version 3.4.1, which contains a fix for this issue. I verified that the new versions fix the octave issue. I am attaching the patch for each PKGBUILD.

Steps to reproduce:

$ octave
> norm(ones(2,3))
** On entry to DORGLQ parameter number 5 had an illegal value
exception encountered in Fortran subroutine dgesvd_

Should be:

$ octave
> norm(ones(2,3))
ans = 2.4495

This task depends upon
