It turned out that it was an ia64 bug. The problem is ia64 relocations
define src_mask and dst_mask to be 0. It is not a problem for normal
ia64 relocations since src_mask and dst_mask are not used. But
src_mask and dst_mask are used in bfd_perform_relocation to relocate
debug sections. I set them to -1LL. I think it should work with
relocations in debug sections for both LP64 and ILP32.
