	* elf/dl-close.c (_dl_close): If object has no r_list (i.e., wasn't
	loaded directly) determine length if l_initfini list by iterating
	over its elements.  Minor optimizations.
	* elf/dl-deps.c (_dl_map_object_deps): Always add own map to l_initfini
	for dependency objects.
	If object was already loaded check whether any of the dependencies
	is already on the relocation dependency list.  If yes, remove the
	latter.  Minor optimizations.
	* elf/dl-lookup.c (add_dependency): Add check for self reference of
	maps here.  Search l_initfini list only if the object was loaded
	directly and not only as a dependency.
	(_dl_lookup_symbol): Add relocation dependency also if object
	is not in global scope.  Remove test for self-reference here.
	(_dl_lookup_versioned_symbol): Likewise.
	* elf/dl-object (_dl_new_object): Cleanup.  Initialize dont_free
	element of first name record.
	* elf/loadtest.c: Add some more test to recognize early if an object
	wasn't unloaded.
	* elf/Makefile: Add rules to build and run reldep5.
	* elf/reldep5.c: New file.
	* elf/reldepmod5.c: New file.
	* elf/reldepmod6.c: New file.

	* elf/reldep2.c: Fix typo.

	* elf/dl-object.c (_dl_new_object): Initialize l_scope and l_scope_max.
