	* elf/dl-debug.c (_dl_debug_initialize): Take extra parameter and
	use it to select the r_debug structure for that namespace.
	* elf/dl-close.c (_dl_close): Adjust call to _dl_debug_initialize.
	* elf/dl-load.c (_dl_map_object_from_fd): Likewise.
	* elf/dl-open.c (_dl_open): Likewise.
	* elf/rtld.c (dl_main): Likewise.
	* sysdeps/generic/ldsodefs.h (struct link_namespaces): Add _ns_debug
	member.
	(_dl_debug_initialize): Add new parameter in declaration.

	* elf/dl-close.c (_dl_close): Make sure auditing callbacks are not
	called for the auditing objects themselves.
	* elf/dl-load.c (_dl_map_object_from_fd): Likewise.
