Update.

	Change ld.so to not use functions which are exported.  One cannot
	interpose them anyway.  Use INT() to mark uses, INTDEF() to mark
	definitions.
	* include/libc-symbols.h: Define INT and INTDEF.
	* sysdeps/generic/ldsodefs.h: Declare _dl_debug_printf_internal,
	_dl_signal_error_internal, _dl_map_object_internal,
	_dl_map_object_deps_internal, _dl_lookup_symbol_internal,
	_dl_lookup_versioned_symbol_internal,
	_dl_relocate_object_internal, _dl_debug_state_internal,
	_dl_start_profile_internal, and _dl_unload_cache_internal.
	* include/dlfcn.h: Declare _dl_catch_error_internal.
	* elf/rtld.c: Use INT for calls to any of the *_internal functions
	above.  Add INTDEF to function definitions.
	* elf/dl-debug.c: Likewise.
	* elf/dl-deps.c: Likewise.
	* elf/dl-dst.h: Likewise.

	* sysdeps/generic/dl-cache.c: Likewise.
	* sysdeps/generic/dl-sysdep.c: Likewise.
	* sysdeps/alpha/dl-machine.h (RTLD_START): Call _dl_init_internal
	instead of _dl_init.
	* sysdeps/arm/dl-machine.h: Likewise.
	* sysdeps/cris/dl-machine.h: Likewise.
	* sysdeps/hppa/dl-machine.h: Likewise.

	* elf/Versions: Don't export _dl_check_all_versions, _dl_sysdep_start,
	and _dl_debug_initialize.
