[PATCH] Change autogen.sh scripts to respect NOCONFIGURE

[Colin Walters]

Background: I'm trying hard to bring continuous integration and testing
to the FOSS stack between linux and gnome-shell.  That means building
from git, not manual integration via tarballs.  The current xorg
autogen.sh scripts just need one minor tweak to match the ones we use in
GNOME.  I've been slowly massaging and harmonizing the ad-hoc
autogen.sh/bootstrap scripts found in various modules.

Could someone just script this patch application across all xorg modules
that have autogen.sh?

Thanks!
