'usbredir' is needed by 'spice-gtk' which is only needed to run the tests for spice. This can be fixed by removing the automated tests configure-flag and removing spice-gtk from the dependencies on i686. If supported-systems is set correctly, will guix try to build without the required package? This is useful in case the dependency is only optional. Trying to build with guix build --system=armhf-linux tells me that I'm x86-64-linux and the same for --system=mipsel-linux. It would be nice if guix build would spin up a qemu instance in this case. It will take me a while to test.
