Random request - could you guys also CC patches to GNOME stuff to me?  I
do review patches to GLib fairly actively.

As far as removing the libelf support; note this means GResource won't
work which in turn means gtk3 won't work (at the moment).

Anyways, a patch to add a configuration option is really, really trivial
if one has a checkout of git, if someone files a bug with a rationale I
can do a patch.
