I suspect the specs files are in STAGESTUFF so that we can find them in the
stageX directories via -BstageX/.  If we don't move them, then it's likely
we won't find the spec file during the stage2/stage3 build.

libgcc does need to get rebuilt at each stage since it can contain langauge
specific stuff which wouldn't have been built during stage1.

I'm not sure how best to address this problem.
