Btw you should be able to link libiberty statically into both cc1
and plugins. You just need to make sure to not export its symbols
from cc1 (may be as easy/complicated/portable as linking
the whole archive).
Note that I do not think Basiles patch is acceptable - it's a gross
hack that involves an API.
