This change broke qemu-for-tests and qemu-2.3.0. In turn, that broke
GRUB, American fuzzy lop, and a bunch of the system tests:
https://hydra.gnu.org/eval/109151

I adjusted the QEMU variants with the attached patch, but the system
test "installed-os" still fails like this:

$ guix environment --pure guix --ad-hoc git
[env]$ make check-system TESTS="installed-os"
Compiling Scheme modules...
