* include/features.h (__USE_FORTIFY_LEVEL): Also set for Red Hat

	GCC 3.4.x-RH >= 3.4.2-8.
	* libio/bits/features.h (printf, fprintf, vprintf, vfprintf): For
	GCC 3.4.x-RH use __builtin___{,v}{,f}printf_chk instead of
	__{,v}{,f}printf_chk.
	* debug/tst-chk1.c (do_test): Deal with GCC 3.4.x-RH not
	being able to recognize subobjects.
