Hi! The x86 EFI stub builds from its own short list of compiler flags instead of KBUILD_CFLAGS, so options added kernel-wide reach it only when someone remembers to add them there too (e.g. for -fms-extensions). Swap it around to remove unwanted options instead, as we do for all the other architectures.
This will let Clang's -fexperimental-late-parse-attributes reach the stub build so that __counted_by() will get parsed without error[1].
