* solib-svr4.h (struct link_map_offsets): Remove l_addr_size,

	l_ld_size, l_next_size, l_prev_size, l_name_size.

	* solib-svr4.c (LM_ADDR_FROM_LINK_MAP): Use extract_typed_address
	to extract addresses from link map.
	(LM_DYNAMIC_FROM_LINK_MAP): Likewise.
	(LM_NEXT): Likewise.
	(LM_NAME): Likewise.
	(IGNORE_FIRST_LINK_MAP_ENTRY): Likewise.
	(elf_locate_base): Likewise.
	(open_symbol_file_object): Likewise.
	(svr4_fetch_objfile_link_map): Likewise.
	(SOLIB_EXTRACT_ADDRESS): Remove unused macro.
	(HAS_LM_DYNAMIC_FROM_LINK_MAP): Test l_ld_offset instead of
	l_ld_size.
        (svr4_ilp32_fetch_link_map_offsets): Don't set removed members.
	(svr4_lp64_fetch_link_map_offsets): Likewise.

	* solib-legacy.c (legacy_svr4_fetch_link_map_offsets): Don't set
	removed members.  Set l_ld_offset to -1 if not present.
