It run just fine. I attached an ebuild with some modifications:
- I modified crunchsys with sed so at it change to /usr/src/linux (my editor don't like sed syntax, but it work).
- I removed 2 not needed symlinks. Even go can be removed, but as they talk about it in the Readme, it is better to keep it.

Thanks for the work,
