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.

libatomic, libgomp, libitc: Fix bootstrap [PR70454]
The recent changes to error on mixing -march=i386 and -fcf-protection broke
bootstrap. This patch changes lib{atomic,gomp,itm} configury, so that it
only adds -march=i486 to flags if really needed (i.e. when 486 or later
isn't
on by default already). Similarly, it will not use ifuncs if -mcx16
(or -march=i686 for 32-bit) is on by default.
