Many GLib based programs do *not* need dconf.  So far, I know of only
two programs in Guix that need dconf.  It is a GNOME thing, not a GLib
thing.

Also, I wouldn't be surprised if one of the transitive inputs of dconf
uses 'glib-or-gtk-build-system', which would lead to a circularity
problem.

That's not true either.

It may be that we should have a 'gnome-build-system' that's based on
'glib-or-gtk-build-system' but adds these extra implicit inputs and
arranges for more environment variables to be set in the wrappers.

Thoughts?
