We no longer bundle APR at all, I don't know that many of these

We no longer bundle APR at all, I don't know that many of these
licenses belong in *this* project repository.

But APR no longer bundles expat at all, making two of those
licenses very archaic - and note they did not reflect the current
LICENSE file contents of the component.

Opinions on leaving it up to repos/asf/apr/apr/trunk/LICENSE
to document other licenses on their project, since we simply are
a consumer of another component, and no longer bundle that?
