Grr.  Ah, well, I guess I'll have to manage the addons better.
I was planning on just not unpacking the thread addon I didn't want
to use, but I realize that might not do for people with their own
fully expanded trees.

Hmm.  Seems kludgy.  I hope I can find a cleaner way.

Two notes:

* someone at IBM did this (see http://gcc.gnu.org/ml/gcc/2004-01/msg00785.html )
but mentions a few patches are needed

* have you tried setting USE_SYSROOT=1 like in x86_64.dat?
