The Guix test 'tests/guix-system.sh' fails on aarch64-linux, like this:

------
+ for example in gnu/system/examples/*.tmpl    
+ grep hurd              
+ echo gnu/system/examples/desktop.tmpl  
+ target=                          
+ guix system -n disk-image gnu/system/examples/desktop.tmpl

------

This manifests while building the 'guix' package itself. Specifically
this derivation:

/gnu/store/i8rjwl9fmm4b6icvry8l2wlz2dwq09ic-guix-1.3.0-17.2a49ddb.drv

... which is based on commit 9f6532c77d35603f5e5d190616e0c6b1740e82bd:

It doesn't happen on x86_64-linux:
