well, the light went on, it wasn't so complicated after all.  since we
run with duplicate=0, the "source" files in the variant dir exist only
in the mind of scons, and then later when a test is run, the test
configuration file isn't there with scons out of the picture.

but surely there is a more best-practice way to say "make sure this file
exists in the variant dir even after scons quits"?
