Uros Bizjak 1ca3683cc6 x86/percpu: Enable named address spaces with known compiler version 
Enable named address spaces with known compiler versions
(GCC 12.1 and later) in order to avoid possible issues with named
address spaces with older compilers. Set CC_HAS_NAMED_AS when the
compiler satisfies version requirements and set USE_X86_SEG_SUPPORT
to signal when segment qualifiers could be used.
