tools/scripts/Makefile.include may expand EXTRA_CFLAGS in a future change. This could alter the initialization of CFLAGS, as the default options "-g -O2" would never be set once EXTRA_CFLAGS is expanded. Prepare for this by moving the CFLAGS initialization before including tools/scripts/Makefile.include, so it is not affected by the extended EXTRA_CFLAGS. Append EXTRA_CFLAGS to CFLAGS only after including Makefile.include and place it last so that the extra flags propagate properly and can override the default options. tools/scripts/Makefile.include already appends $(CLANG_CROSS_FLAGS) to CFLAGS, the Makefile appends $(CLANG_CROSS_FLAGS) again, remove the redundant append.
