I have sent this to the lkml, it seems to have been pushed to the back
burner. This is a major issue effecting users/developers that are
working on a much more security enhanced system. This means any gentoo
user running a hardened toolchain will have problems building a kernel
that works as expect. This patch does nothing but pass the macro
- -D__KERNEL__ to ensure that hardened toolchain drops back to that of a
vanilla toolchain to prevent unexpected compile problems in the kernel.
