In its current form this is very hard to implement because it requires
us to "unparse" the options, including removing any shell quoting.
It wasn't implemented at all for the libvirt backend.
Also contrary to the documentation, the configure script did not use
these options for testing, but constructed its own set of qemu test
options.
