This configuration is for timing how we handle the NxM interaction when
we build a lot of targets from a lot of source files.

We create a list of $TARGET_COUNT target files that will each be built by
copying a file from a corresponding list of $TARGET_COUNT source files.
The source files themselves are each built by a Python function action
that's the equivalent of "echo contents > $TARGET".
