commit 2d6233b60e419059240e054e40fc6ece6fd94929
Author: Bernhard M. Wiedemann <bwiedemann@suse.de>
Date:   Mon Mar 25 11:12:56 2019 +0100

Sort input file list
    
    so that mpich builds in a reproducible way
    in spite of indeterministic filesystem readdir order
    
    See https://reproducible-builds.org/ for why this is good.
    
    Without this patch,
    README.envvar, /usr/lib64/mpi/gcc/mpich/bin/mpivars and other
    output files varied between builds.
