[Chun-wei Fan <fanchunwei src gnome org>]

commit 49707510572f1d1b86ac2e7a999abdbfd50d6897
Author: Chun-wei Fan <fanchunwei src gnome org>
Date:   Mon Sep 10 10:57:52 2018 +0800

    Fix reference documentation generation
    
    * atk/atkmm/filelist.gmake.am:
    * atk/atkmm/Makefile.am: Split out again the automake-specific part
    which we splitted out from atk/atkmm/filelist.am previously into a
    file of its own.
    * doc/Makefile.am: Include atk/atkmm/filelist.gmake.am so that we
    get a complete set of documentation generated.
