* coffcode.h (bfd_coff_backend_data): Add new field
_bfd_coff_pointerize_aux_hook. (coff_pointerize_aux_hook): Define as a function if RS6000COFF_C or I960, and as 0 otherwise. (bfd_coff_std_swap_table): Initialize new field. * libcoff.h: Rebuild. * coffgen.c (coff_pointerize_aux): Change parameters to take symbol pointer instead of type and class, and to take aux index. Call _bfd_coff_pointerize_aux_hook if it is defined. (coff_get_normalized_symtab): Always call coff_pointerize_aux. * coff-alpha.c (alpha_ecoff_backend_data): Initialize all fields. * coff-mips.c (mips_ecoff_backend_data): Likewise.
