Thanks! I can confirm this behavior also happens on my machine, running
Guix on a foreign distro (Ubuntu, with kernel 5.11.0-25-generic). I ran
into the problem while trying to build ‘bootstrap-tarballs’, and with
your patch it works.

Just one suggestion: what about only deleting the problematic test if
‘%current-system’ is "i686-linux"?
