x86: Error on -fcf-protection with incompatible target
GCC issues an error on -fcf-protection with incompatible target. CET
is enabled in run-time libraries on x86 when GCC is configured with SSE2
enabled. But 32-bit libitm/libgomp/libatomic are hardcoded to
compile with -march=i486 which is incompatible with CET. We should
compile libitm/libgomp/libatomic -march=i486 only if the default -march=
is lower than i486.
