Subject: [PATCH 13/21] Build system: Always append CFLAGS at the end

The build system sets -g -O2 -fno-strict-aliasing -pipe by default. We append the enviromental CFLAGS at the end to allow the user to override the default CFLAGS

I'm going to think about this proposed change for a while because
it might break certain scenarios. Please test this change and other build changes via the testscripts/build/test_* scripts before sending them out for review.
Thanks,
