Unfortunately, simply adding 'vpath' to config.mak doesn't solve the problem.
I tried a couple of things, however when I tried moving my host machine's
libskarnet.a out of the default library path on that machine, make failed with
this error:

make: *** No rule to make target '-lskarnet', needed by 'background'. Stop.

up the cross target's artificial library path over the host machine's
