One of the execute_command_line tests currently runs `cat` on an invalid file and checks its return value, but since we don't control `cat` or the user's path, the return value might not be reliably stable on a per-platform basis. For example, if `git` is installed on Windows in certain configurations it adds a directory to the path containing a `cat` with a different set of error codes to the default Windows one. This patch changes the test to use the `not` binary built by LLVM for testing purposes, which should always return 1 on any platform regardless of the user's environment.

I guess my assumption that the tests are always run at the top of the build directory is incorrect. I'll have to work out how to get the path to the top level build dir. |
The not binary will always be placed in this directory.
