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.
Bug: https://gcc.gnu.org/PR117952
Closes: https://bugs.gentoo.org/933772
