Both questions are valid:

a) If I build distcc and I have x11 disabled, it shouldn't break.

b) Should qemu include distcc?

Traditionally, qemu-config does pull it in. Why? The qemu scripts allow
pass through of compilation to the build system instead of doing it
under emulation for a significant speed up in compile time. It was
originally felt that it should therefore maximally autoconfigure that
stuff transparently to the user.

If we don't think that is useful we can drop it. That is a separate
discussion to a) which seems to be the contentious problem and solving
b) is just hiding from the issue.

and the rest (resolving the various packaging conflicts so that
distcc-gnome only packages the gnome pieces and removes everything
else).

To put this quite simply, I think there is no good reason we shouldn't
use the mechanism we've selected to handle this kind of problem. We
should have defaults the reflect backwards compatibility. Other than
that where is the problem other than a general objection to
PACKAGECONFIG?
