	* elf/linux-compat.c (_init): Pass reloc_addr arg to _dl_lookup_symbol.

	* elf/dl-lookup.c (_dl_lookup_symbol): Use l_searchlist.

	* elf/dl-deps.c: New file.
	* elf/Makefile (rtld-routines): Add dl-deps.
	* elf/link.h: Declare _dl_map_object_deps, _dl_open.
	* elf/rtld.c (dl_main): Use _dl_map_object_deps.
	* elf/dlopen.c: Use _dl_open.

	* elf/rtld.c (dl_main): Remove BEFORE_RTLD variable and list
	frobnication based on its value.  Detach RTLD_MAP from the chain if
	its l_opencount is zero after loading deps.

	* elf/dlfcn.h (RTLD_BINDING_MASK): New macro.

	* elf/link.h (struct link_map): Replace l_deps_loaded flag member with
	`struct link_map **l_searchlist' and `unsigned int l_nsearchlist'.
	* 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
	elt that is not null.
	* elf/dl-reloc.c (_dl_relocate_object): Pass proper SCOPE array.
	* elf/dl-runtime.c: Likewise.
	* elf/dlsym.c: Likewise.
	* elf/rtld.c (dl_main): Likewise.

	* elf/dl-minimal.c (realloc): Support realloc of the block most
	recently returned by the minimal malloc.

	* intl/localealias.c, intl/dcgettext.c [_LIBC]: Define HAVE_ALLOCA.
