* Added magma package
* Incorporated Serban's change
* Remove deleted files
* argparse.py
* Sync forked Spack repo in github
* Use reported version of IBM XL Fortran compiler for compiler versions
>= 16.0.
Starting with the April 2018 release, the IBM XL C and Fortran
compilers report the same version, 16.0. Consequently, there is
no need to downgrade the Fortran compiler version to match that
of the C compiler.
* Eliminate blank lines.
* Update the Spectrum MPI package.py file to specify the correct compilation
scripts for the PGI compilers.
