Thanks to dariqq for finding the upstream bug report about this build
failure:

https://lore.kernel.org/stable/d6947457-c1e7-476a-9857-f4a6450b9d94 <at> suse.com/

Looks like the build wasn't test upstream.

We'll wait for it to get fixed upstream, since it doesn't seem like this
kernel is used on i686-linux by anyone in Guix.
