[Christoph Reiter <creiter src gnome org>]

commit 83f9c90befe964c91ea21dab9b9ea24948fd5715
Author: Bernhard M. Wiedemann <bwiedemann suse de>
Date:   Sat Oct 20 21:10:32 2018 +0200

    Sort input file list
    
    so that _gi.so builds in a reproducible way
    in spite of indeterministic filesystem readdir order
    
    See https://reproducible-builds.org/ for why this is good.
