Subject: deal with endian-ness in mach-o non-scattered relocs.
BFD:
* mach-o.c (bfd_mach_o_swap_in_non_scattered_reloc): New.
(bfd_mach_o_canonicalize_one_reloc): Swap non-scattered reloc
bit-fields when target and host differ in endian-ness. When
PAIRs are non-scattered find the 'symbol' from the preceding
reloc. Add FIXME re. reloc symbols on section boundaries.
(bfd_mach_o_swap_out_non_scattered_reloc): New.
(bfd_mach_o_write_relocs): Use bfd_mach_o_encode_non_scattered_reloc.
include/mach-o:
* external.h: Add comments about relocations fields. Add macros
for non-scattered relocations. Move scattered relocation macros to here.
* reloc.h: Remove macros related to external representation of reloc fields.
