bug#33312: Guix: many tests fail when building on 0.15

[swedebugia]

Hi

I want to contribute to guix with patches and at the same time keep my 
GuixSD on 0.15.

To archive this I created and followed the following guide in GuixSD in 
Qemu:

https://gitlab.com/swedebugia/guix-notes/blob/master/BUILD.org

Following it Guix 21335fdbec68b4cfb19d8a0ae0877ec81c84ad9c builds fine.

BUT

running make check I got a lot of failed tests and no testlog:
