	* Makefile.def (bfd, opcodes, libstdc++-v3, libmudflap): Set lib_path.
	* Makefile.tpl (SET_LIB_PATH, REALLY_SET_LIB_PATH): Remove.
	(HOST_EXPORTS, STAGE_HOST_EXPORTS, TARGET_EXPORTS): Set $(RPATH_ENVVAR).
	(HOST_LIB_PATH): Generate from Makefile.def.
	(TARGET_LIB_PATH): Likewise.
	(Old bootstrap targets): Include TARGET_LIB_PATH into RPATH_ENVVAR.
	* Makefile.in: Regenerate.
	* configure.in (set_lib_path, SET_LIB_PATH, SET_GCC_LIB_PATH): Remove.
	(RPATH_ENVVAR): Include Darwin case.
	* configure: Regenerate.
