[Christoph Reiter <creiter src gnome org>]

commit de27e3a82552d3d8cbf665d560f670fa3989ab7f
Author: Bernhard M. Wiedemann <bwiedemann suse de>

    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.
