toolchain.eclass: pass -fcf-protection=none for stage1 builds with Clang GCC's host_detect_local_cpu returns NULL when built with Clang (see bug for details) so pass -fcf-protection=none for stage1 (where it doesn't really matter anyway) to avoid a failure when -march=native ends up resolving to nothing (b/c NULL) and then erroring out as CET isn't supported for the baseline -m32 CPU.
