[buildd] q650 stable chroot down

[Michael Schmitz <schmitz@mail.biophys.uni-duesseldorf.de>]

In an attempt to get gcc-3.4 to build for stable, I foolishly moved the
stable chroot to a recenty added disk on q650. The disk promptly threw
media errors on the first build :-(

I'll take down the stable chroot for repair, and try to low-level format
the flaky disk. The gcc-3.4 build has been moved to hobbes hoping it'll
finish there, but I'll have to get things sorted on q650 before reenabling
it fully.

If someone else could pick up the slack, please go ahead ...
