* coff-mips.c (mips_relocate_section): When relaxing, adjust local
relocs against the .text section as required.
* ecofflink.c (bfd_ecoff_debug_accumulate): When relaxing, adjust
PDR addresses as required.
* ecoff.c (ecoff_emit_aggregate): Take fdr argument. Map fdr
index through rfd map if it exists. Check for a couple of cases
which gdb handles specially. Change all callers.
