* elf64-ppc.c (ppc64_elf_size_dynamic_sections): Add dynamic
DT_PPC64_OPD and DT_PPC64_OPDSZ tags.
(ppc64_elf_finish_dynamic_sections): Set values for them.

to front of message. Unify messages with elf32-arm.h. Use
commas where neccessary.

ERROR in messages. Unify messages with coff-arm.c. Correct
VFP/FPA error message.

APCS-32 for translation.

relocate .opd without reloc entries. FIXME: the dynamic linker
will need to know where and how large .opd is via a couple of new
DT_PPC64_* tags, or perhaps just with one reloc that specifies the
start of .opd via its offset and the size via its addend. Also,
