* 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.
