Hello,

The command `guix shell -s riscv64-linux -Kc $(($(nproc)/2)) git` fails due to test failures while building Python 3.10.7. Notably, creating a shell with just Python (so, swapping "python" for "git" in the command) works fine.

Here is my channel information:
```

(channel

(name 'guix)

(url "https://git.savannah.gnu.org/git/guix.git")

(branch "master")

(commit

(openpgp-fingerprint

```

I have attached the build log as well.

Thanks,
Juli
