[PATCH] dl-deps.c fix

[Jakub Jelinek]

Hi!

L->l_initfini is sometimes created zero terminated, sometimes not.
This can cause accessing l_initfini beyond the end of the allocated string
(seen in _dl_fini) and things then depend on the stage of the noon and
program may crash (seen as well).

	* elf/dl-deps.c (_dl_map_object_deps): Zero terminate L->l_initfini
	always.
