gnu: scalapack: Update to 2.1.0.
* gnu/packages/maths.scm (scalapack): Update to 2.1.0. [source]: Remove "scalapack-blacs-mpi-deprecations.patch" and add "scalapack-gcc-10-compilation.patch". [arguments]: Add 'skip-faulty-test' phase. * gnu/packages/patches/scalapack-blacs-mpi-deprecations.patch: Remove. * gnu/packages/patches/scalapack-gcc-10-compilation.patch: New file. * gnu/local.mk (dist_patch_DATA): Adjust accordingly.
