* stdio-common/_itowa.c: Don't compile _itowa for 64-bit

	platforms.
	* stdio-common/_itoa.c: Don't compile in _itoa and _fitoa for
	64-bit platforms.
	* malloc/mtrace.c (tr_where): Use _fitoa_word instead of _fitoa if
	possible.
	* posix/wordexp.c (parse_arith): Use _itoa_word instead of _itoa
	if possible.
