Makefile: Disable undefined-optimized and tautological features
Wundefined-optimized option was introduced by Qualcomm,
but there are other options in kernel to test
undefined behavior. So disable undefined-optimized feature
by adding -Wno-undefined-optimized to CFLAGS. Also
tautological-constant-out-of-range-compare is not getting
disabled with tautological-compare option disable, so disable
tautological-constant-out-of-range-compare feature explicitly.
