I would just write a test OS definition, and then run:

  ./pre-inst-env guix system build test.scm -nd -s armhf-linux

From there, you can inspect the ‘linux-module-database’ derivation,
check its system type, and check the kmod referred to in its “-builder”
file (is it the file name of the armhf-linux kmod?).

Likewise for cross-compilation.

HTH!
