gnu: petsc: Link against OpenBLAS rather than LAPACK.
OpenBLAS performs better than LAPACK, the reference implementation. This is also consistent with the choice of BLAS/LAPACK implementations made in most other packages. * gnu/packages/maths.scm (petsc)[inputs]: Replace LAPACK by OPENBLAS. [arguments]: Pass "--with-openblas=1".
