x86: Also check if -fcf-protection works

When defaulting CET run-time support to auto, check if -fcf-protection
works.  Even if the stage1 GCC doesn't support -fcf-protection, since
the final GCC does, CET run-time support will be enabled by default if
binutils support CET.

--disable-cet seems to be a workaround, it looks like the configury fails to
check for host compiler support (or alternatively --disable-cet should be the
default for stage1?)
