Yes, this is a “known problem”:

  https://issues.guix.gnu.org/43857

The problem is that the build environment on GNU/Hurd has yet to be
specified, which is what the patch above was partly trying to address
(though I think we could do better than spawn one firmlink translator
per store item…).

The “Isolated build environments” section of
<https://guix.gnu.org/en/blog/2020/childhurds-and-substitutes/>
discusses the broader issue.

If you’d like to get some Hurd hacking done, here’s a good opportunity.
