	* elf/Makefile (routines): Add dl-origin.
	(tests): Add origtest.  Add dependencies for the program.
	* elf/Versions (ld.so) [GLIBC_2.1.1]: Add _dl_origin_path,
	_dl_platformlen, _dl_dst_count and _dl_dst_substitute.
	* elf/dl-deps.c (expand_dst): New macro.  Expand DSTs in filename.
	(_dl_map_object_deps): Use expand_dst to expand DSTs in DT_NEEDED,
	DT_AUXILIARY, and DT_FILTER filenames.
	* elf/dl-load.c (expand_dynamic_string_token): Explode into
	two functions and three macros.
	(_dl_dst_count, _dl_dst_substitute): New functions.
	* elf/dl-dst.h: New file.

	* elf/dlopendoit.c: Likewise.
	* iconv/gconv_dl.c: Adapt call of _dl_open.
	* nss/nsswitch.c: Likewise.
	* elf/origtest.c: New file.
