From GDB's point-of-view, as long as we have access to the .so that is
built that's all GDB wants. So whichever stage it is produced should be
fine.  My archaeology into the source repository has not revealed why
we needed bootstrap.  Perhaps we included it out of a sense of
paranoia for testing.  I've CC'd Tom on this, so he may have an
opinion or insight.  From my point of view, I see no value in
bootstrapping libcc1 now.  It's not a required build to bootstrap GCC.
