      There's a gentoo bug for this here but I figured I'd put one up here as well, in case there's a funtoo-specific issue or fix involved. Feel free to delete if that's wrong.

      On hardened profile, using hardened kernel, ati-drivers-15.12 fails to build with the error below. If I switch off hardened to gentoo-sources, and disable the pax_kernel USE flag, it builds fine, so this is likely a hardened issue. I've observed this behavior from kernel 4.3 up to 4.5. The build log is below.
