* sysdeps/mach/hurd/dl-sysdep.c (_dl_sysdep_start): If started by

	kernel with args on stack, point _dl_hurd_data at zero data
	instead of garbage.  When ld.so run as program, grok args
	-LIB=MEMOBJ and pre-load shared object files found in memory
	objects loaded by the boot loader.

	* elf/link.h (struct link_map): New member `l_entry'.
	(_dl_map_object, _dl_map_object_from_fd): Remove last arg ENTRY_POINT.
	* elf/dl-load.c (_dl_map_object, _dl_map_object_from_fd): Remove
	last arg ENTRY_POINT.  Store the entry point location in the
	`l_entry' member of the new map.
	* elf/rtld.c (dl_main): Don't pass USER_ENTRY arg to
	_dl_map_object.  When run as program, set *USER_ENTRY to L->l_entry.
	* elf/dl-init.c (_dl_init_next): Don't pass ENTRY_POINT arg to
	_dl_map_object.
