I don't think there are issues with unit tests. I just thought
it was pointless to link qdev-hotplug.o into unit tests binaries
if no hotplug handler object is created by them.
What do you think? Should I keep qdev-hotplug.o and hotplug.o in
the unit tests binaries?

I think that would work. I'll do that in v2, thanks!
