Bug 1293234 - Use octal notation for permission modes in the build system; r=gps As of Python 3, decimal notations of octal values for permission modes are no longer permitted and will result in a `SyntaxError` exception (`invalid token`). Using the proper octal notation which is also Python 2.7 compatible will fix this issue.
