Agreed. However, I don't see when exactly this message would be
triggered. Cleber, on which use cases do you expect
pick_default_qemu_bin() to be called?
In an ideal world, any testing runner/tool should be able to
automatically test all binaries by default. Can Avocado help us
do that? (If not, we could just do it inside a
./tests/acceptance/run script).
