"p *(struct ppc_link_hash_entry *) h" might be useful here, if you can recreate
the problem.

Also, "p *abfd" here.  And "p abfd->filename" then (outside of gdb) report the
output of "file" for this file.  There is some possibility you might be
attempting to link in a non-ppc64 file somehow.

Another useful debug exercise would be to use "watch" on the h->oh field of the
symbol involved here to see where it is being set to -1.
