Attached a .config that works OK here with the latest tip of the repository.

This is caused by the removal of the symlinks, as you found out. It seems
that those symlinks are needed, after all, and the attached patch fixes that
for me. Care to test and report back, please?

NB. The symlinks are needed because, if absent, the build breaks when
building gcc, as it complains that it can't find libiberty.an (whatever
it is) that it is just building.
