Normally, /bin/cc would be used to build the build libiberty, and
i686-linux-gcc would be used to build the target library.  Ideally,
i686-linux-gcc would have been built from the same sources as you're
building the ia64 cross with, in case there are interface issues.

It would have a makefile that works with its toplevel files.  If you
are mixing and matching sources from two different points in time,
you're on your own.
