bug#47451: Guix pull building lz4-1.9.3 fails

[Bone Baboon]

I am getting an error message that tells me to report it to this Guix
bug mailing list.

After reading the Specifying Additional Channels section of the Guix
manual I created  `~/.config/guix/channels.scm` with these contents: 

```
(cons
 (channel
  (name 'openvpn-2-4-9)
  (url "https://git.savannah.gnu.org/git/guix.git";)
;  (commit "33c140e0fb3ddcd6ce05c02bc00df102830ecbd6"))
  (commit "c5a2b70135c9830e9c3051ddf4a096f9a80eb952"))
 %default-channels)

```

When I run `guix pull --no-substitutes` I get this error message below.

I get the same error message if I use commit
c5a2b70135c9830e9c3051ddf4a096f9a80eb952 and run `guix pull
--no-substitutes`.

When I run `guix describe` on the computer that is getting this error it
outputs:
```

    branch: master
    commit: 53dd99bc0b2e23c5463b4cb95546fd438a72d229
```

With the same channels.scm file with the
33c140e0fb3ddcd6ce05c02bc00df102830ecbd6 commit on another x86_64
computer if I run `guix pull` there is no error message.
