* elf/dl-deps.c (_dl_map_object_deps): Set MAP's mark bit before loop.

	Set mark bits of deps as opened, instead of as scanned.

	* elf/rtld.c (dl_main): Remove _dl_rtld_map from chain unconditionally.
	Then if it has a nonzero l_opencount, add it back in search order.

	* elf/dl-load.c (_dl_map_object): Don't use _dl_loaded's DT_RPATH if
 	it ain't got one!
