commit 198f1ba0d790ee18b710a876f3a81837a76cff69
Author: Philip Chimento <philip chimento gmail com>

    build: Modernize autogen.sh
    
    This gets rid of the dependency on the old gnome-autogen.sh and moves
    instead to the suggested autogen.sh given as an example in the
    gnome-common migration guide:
    https://wiki.gnome.org/Projects/GnomeCommon/Migration
    
    https://bugzilla.gnome.org/show_bug.cgi?id=772027
