That sounds reasonable, if we're guaranteed always to have a libdl.
However, the fact that it's not needed on F12 suggests that we should
be adding it only when necessary (hence a configure-time test).
I hit that same problem a few hours ago, but haven't yet gotten to it.
I'm assuming that the problem is related to:

The virtualbox driver seems like it needs -ldl, but this was only
being provided implicitly before, but now needs to be given
explicitly.
