	* malloc/mcheck.c (freehook, reallochook): Handle null pointer args.

	* hurd/hurdsig.c (_hurd_internal_post_signal): When setting ACT to
	`ignore, resume the thread if SS_SUSPENDED, regardless of old action.

	xstrdup; fix memory leak.
	(lr_close): Fix memory leak.

	* hurd/hurdsig.c (_hurd_internal_post_signal): When turning the action

	* elf/link.h (struct link_map): Replace l_deps_loaded flag member with
	`struct link_map **l_searchlist'.
	* elf/dl-lookup.c (_dl_lookup_symbol): Make SYMBOL_SCOPE arg an array
	of two link_map ptrs.  Search the maps in the l_searchlist of each
	of the two elts that is non-null.
	* elf/dl-reloc.c (_dl_relocate_object): Pass proper SCOPE array.
	* elf/dl-runtime.c: Likewise.
