	* csu/abi-note.S: Use OS and version separately, include config.h.
	* elf/dl-load.c (_dl_osversion): New.
	(_dl_map_object_from_fd): Kill some warnings.
	(open_verify): Check .note.ABI-tag of the library if present.
	* elf/Makefile (CPPFLAGS-dl-load.c): Add -I$(csu-objpfx).
	* elf/cache.c (struct cache_entry): Add osversion.
	(print_entry): Print osversion.
	(print_cache): Pass osversion to it.
	(compare): Sort according to osversion.
	(save_cache): Set osversion.
	(add_to_cache): Add osversion argument.
	* sysdeps/generic/ldconfig.h (add_to_cache, process_file,
	process_elf_file): Add osversion argument.
	* elf/readlib.c (process_file): Likewise.
	* sysdeps/generic/readelflib.c (process_elf_file): Likewise.
	* sysdeps/unix/sysv/linux/ia64/readelflib.c (process_elf_file,
	process_elf32_file, process_elf64_file): Likewise.

	process_elf32_file, process_elf64_file): Likewise.
	* sysdeps/unix/sysv/linux/sparc/readelflib.c (process_elf_file,
	process_elf32_file, process_elf64_file): Likewise.
	* elf/ldconfig.c (manual_link): Pass it.
	(search_dir): Issue diagnostic if two libs with the same soname in
	the same directory have different .note.ABI-tag.  Record osversion in
	dlib_entry and use it from there.
	(struct lib_entry): Remove.
	(struct dlib_entry): Add osversion.
	* sysdeps/generic/dl-cache.c (_dl_load_cache_lookup): Check
	osversion.

	* sysdeps/unix/sysv/linux/configure.in: Define __ABI_TAG_VERSION.
	* Makerules (build-shlib-helper, build-module-helper): New.
	(build-shlib, build-module-helper): Make sure .note.ABI-tag comes
	early.
	* config.h.in (__ABI_TAG_VERSION): Add.
