I have trouble with this one.  Tried to declaring the modules as "input"
to make sure meson will only run qemu-modinfo when it is done building
the module.  But now and then I get build errors because qemu-modinfo
runs in parallel to a module build and qemu-modinfo throws an read error
because of that.

Any clue what is going on here?

thanks,
