How exactly does this work w=
ithout emulating the system in question?

It works by not performing any work except compilation -- Guix' responsibility would only be to cross-compile and install the tests (_not_ running them), you are supposed to install the cross-compiled thing (including tests) on the target system and run the tests on the target system.
