autoconf-gnerated Makefiles rely on VPATH for building outside the
source tree, which will interfere with this usage. Also, VPATH
functionality isn't very portable across Make implementations. These
would make it harder for us to integrate upstream. I'd have to think a
while about how best to do this without using VPATH.
