Why are we adding binaries to a repo? such as python.exe, binlevel.exe, etc?

[twangboy]

Most of the binaries are just junk... required by the installer code because it's expecting a file with that name. The Python binaries are necessary because the build script runs the python to get the arch it was built for. In a typical environment, this would be the Python.exe/.dll created by relenv. For the test environment, we don't really care. It just needs to return the arch of the system.
