Done and pushed as cf2ac04f13d9266c7c8a2ebd2e85ef593231ac9d.

It could be use to achieve the same result as the <native-qemu> package
you proposed:
#~(… #+(with-parameters ((%current-system %system)) qemu) …)
However, the issue I mentioned before with this approach remain:
[…] now the result of:
guix system build -s armhf-linux -d …
would be dependent on the actual system type. In other words, the
result would be different if you run it on armhf-linux, if you run it on
x86_64-linux, or if you run it on i686-linux. Not great.
Thanks for your feedback!
Ludo’.
