Thanks Jim, Dan. Discussing this has clarified my thinking on this a lot.
Originally I wanted to test whether a particular instance of libvirt had support for the remote driver. Since the drivers don't usually export symbols directly from the library, it seemed that what I needed was a version check function. In fact that's wrong: even later versions of libvirt could be compiled --without-FEATURE. The only way to do this reliably is to test for presence of drivers at runtime. virGetVersion allows me to do this for drivers.
Having said that, I think AC_LIBVIRT_PYTHON could be a useful check for virt-manager.
