register-closures is being done inside the VM and needs sqlite, which we
don't have because it's for the wrong architecture.  So as long as we
avoid sqlite, we can cross-build a working VM.

True...but currently Hurd is the only image that we are trying to build
in this weird way, i.e., using a native qemu!  Other cross-builds of
vm-images are done using qemu-TARGET, only for the Hurd that does
not work.

Greetings,
Janneke
