If you look higher in the build log, there’s probably an error message
from ‘patch’ indicating that it failed to apply one of the patches.
Could you check that?

You can access the full log by opening the file returned by:

  guix build --log-file /gnu/store/r6lja7k5y2984kbzzkz94fzsmbhfbs9g-linux-libre-4.8-gnu.tar.xz.drv

HTH!
