	* elf/Makefile (distribute): Add dl-origin.h.
	* sysdeps/generic/dl-origin.h: New file.
	* sysdeps/unix/sysv/linux/dl-origin.h: New file.
	* elf/link.h (struct link_map): Add l_origin field.
	* elf/dl-load.c (expand_dynamic_string_token): New function.
	(decompose_path): Remove WHERE argument, take link map pointer instead.
	Call expand_dynamic_string_token instead of local_strdup to make copy
	of rpath.
	(_dl_init_paths): Call decompose_path with correct argument.
	(_dl_map_object_from_fd): Define static is EXTERNAL_MAP_FROM_FD is
	not defined.
	Check EI_OSABI and EI_ABIVERSION fields in header.
	(_dl_map_object): Call decompose_path with correct argument.
	Call expand_dynamic_string_token instead of local_strdup to also
	expand DST.
	* elf/dl-object.c (_dl_new_object): Determine l_origin for all maps
	but the main one.
	* elf/dl-support.c: Define _dl_origin_path.
	* elf/rtld.c: Likewise.  Set _dl_origin_path based on LD_ORIGIN_PATH.

	* elf/dl-close (_dl_close): Free l_name and l_origin.

	* sysdeps/i386/useldt.h (THREAD_GETMEM, THREAD_SETMEM): Use P
	modifier in asm, not c.

	* sysdeps/mach/hurd/Makefile [subdirs==elf]: Define CFLAGS-dl-load.c
	to -DEXTERNAL_MAP_FROM_FD to make _dl_map_object_from_fd extern.
