x86/percpu: Enable named address spaces for all capable GCC versions
Enable named address spaces also for GCC 6, GCC 7 and GCC 8
releases. These compilers all produce kernel images that boot
without problems.
Use compile-time test to detect compiler support for named
address spaces. The test passes with GCC 6 as the earliest
compiler version where the support for named address spaces
was introduced.
