Update.
	* elf/dl-deps.c (_dl_map_object_deps): Change return type and remove
	last parameter.  Move code to add map to global scope from here...
	* elf/dl-open.c (dl_open_worker): ...here.
	* elf/ldsodefs.h: Adjust declaration of _dl_map_object_deps.
	* elf/rtld.c: Adjust call to _dl_map_object_deps.
