* sysdeps/unix/sysv/linux/Dist: Add sys/klog.h.

	* elf/dl-open.c (_dl_open): Remove PARENT argument, pass null.
	* elf/link.h: Update prototype.
	* elf/dl-load.c (_dl_map_object): If dependents' DT_RPATHs don't find
	NAME, try the DT_RPATH of the executable itself if dynamic.
	* elf/dlopen.c (dlopen): Don't pass first arg to _dl_open.

	* elf/dl-load.c (_dl_map_object): Exit DT_RPATH checking loop when an
	open succeeds.

	* Makerules (build-shlib): Give -L opts for each elt of $(rpath-link).

	* sysdeps/mach/hurd/Makefile (sysdep-LDFLAGS): Variable removed.
	(rpath-link): Append to this instead.
