x86/build: Turn off -fcf-protection for realmode targets
[ Upstream commit 9fcb51c14da2953de585c5c6e50697b8a6e91a7b ]
The new Ubuntu GCC packages turn on -fcf-protection globally,
which causes a build failure in the x86 realmode code:
cc1: error: ‘-fcf-protection’ is not compatible with this target
Turn it off explicitly on compilers that understand this option.
