bug#30896: Guix pull problems on armhf

[Jelle Licht]

I have been running the binary Guix installation on top of Armbian 
on my
Rockchip RK3288 (armhf) based computing platform.

Up till about ~8 days ago, guix pull worked as intended. Recently,
running guix pull leads to the following error message
`./guix/build/pull.scm:44:20: ./guix/build/pull.scm:44:20: Throw 
to key
`match-error' with args `("match" "no matching pattern"' [1]


I already checked that re{moving,naming} 
`$HOME/.config/guix/latest'
does not change anything. Neither does running `./pre-inst-env 
guix
pull' from a git checkout.
