Fix romstage creation with gcc 4.6 and CAR targets
newer gcc versions generate ".section .text" instead of just ".text" in their assembler output. This patch makes sure that we don't end up with a superfluous ".section" that makes the build fail. Add -Wno-unused-but-set-variable to CFLAGS if the flag exists.
