Did that, restarted the whole thing, still seeing undefined ref errors.

I see that those functions should come from libiberty, and I see libiberty.a in the above link. In the meantime, if you have the gcda files and preprocessed source or whatever I need to reproduce the failure and can attach them to the bug that would be great.
