I take it this is not built by default. Should it be?

Does something similar apply to the other *front ?

know any reason for not enabling pcifront by default.

Right, here is a patch.

Fix test application link when various fronts are not enabled.

When fronts are not enabled, the test application needs to disable the
corresponding tests.
