Just curious, what's the use case for Qemu on the target? I would have
seen Qemu as something useful on the host, but on the target?

Doh? You just need to do:
QEMU_DEPENDENCIES += host-python
and that's it.

You can drop this.

Just don't implement the UNINSTALL_TARGET_CMDS in this case.
Since quite some time, we're considering dropping the
UNINSTALL_TARGET_CMDS and CLEAN_CMDS altogether.
