* 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.
