This won't really check very much. What we really want is to create
a simple test case, that links to the main libvirt.so (ie not the
test_libvirt.so which omits symbol versions), and then does a
dlopen() on each module we built & reports error if any fail.

I'd also be inclined to just add '--with-driver-modules' to the
existing autogen.sh line in autobuild.sh, rather than doing yet
another clean+build cycle.

Actually, we shouldn't need these here. Ideally we'd get to the
point where we don't need *any* of these --without-XXX options
in autobuild.sh. It should be automatically figuring out what
is available itself.  Only in the RPM builds should we have
use --with and --without flags to strictly control what is
built.
