Refering to C binaries from Python code is going to be a common need. Add a helper to convert from path in relation to the test. Meaning, if the test is in the same directory as the binary, the call would be simply: cfg.rpath("binary").
The helper name "rpath" is not great. I can't think of a better name that would be accurate yet concise.
