debugging features and the RELENG_5

Hello!

I'm reading in http://www.freebsd.org/releases/5.3R/schedule.html
that the debugging for RELENG_5 is off since September 7th. However,
the src/lib/libc_r/Makefile and some other makefiles still have things
like:

	CFLAGS+=-D_LOCK_DEBUG
	CFLAGS+=-D_PTHREADS_INVARIANTS

should not these be disabled too? Thanks!
