When i suggested binding it in Gtk3.pm in 2013, Torsten complained
about how to reliably detect platforms that have the X11 backend
installed
So adding a subpackage for those who really need it would be the best
solution IMHO
Then it would be the callers job to check if it loads successfully or
not and to fallback if possible
