[devhelp/wip/swilmet/build-system-update: 1/3] build: don't use gnome-autogen.sh (deprecated)

[Sébastien Wilmet <swilmet src gnome org>]

commit f3542eb092bd72fe55bb64757add2c407b26d645
Author: Sébastien Wilmet <swilmet gnome org>
Date:   Thu Nov 3 14:36:39 2016 +0100

    build: don't use gnome-autogen.sh (deprecated)
    
    gnome-common is deprecated, use the new autogen.sh as provided at:
    https://wiki.gnome.org/Projects/GnomeCommon/Migration
    
    From the template, the call to glib-gettextize has been removed. The
    call to intltoolize is kept because Devhelp still uses intltool.
