If you look higher in the build log, there=E2=80=99s probably an error mess=
age
from =E2=80=98patch=E2=80=99 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-l=
ibre-4.8-gnu.tar.xz.drv

HTH!
