Oh, we're not replacing the apr and neon Makefiles, we'll just invoke
them. I don't think anyone wants to take on *that* level of
infiltration into external projects. :-) So we're still using
"recursive" make in that limited sense.
The new build system doesn't currently invoke them, afaik, but that's
just a buglet, not a planned behavior.
