* aoutx.h (translate_from_native_sym_flags): Now handles indirect

	symbols in a better way. (translate_to_native_sym_flag): Set the
	N_INDR bit when necessary. (aout<>slurp_symbol_table): Maintain
	indirect state.
	* section.c: Added BFD_IND_SECTION_NAME and bfd_ind_section.
	(bfd_make_section): Cope with new builtin section.
	* syms.c (bfd_decode_symclass): Can now print indirect section
	info.
