This gets Xcode to dynamically link the Swift stdlib. We then copy the binary out and it is installed standalone

Xcode always statically links the Swift stdlib into CLI applications. Combined with the dynamically-linked stdlib loaded by the various frameworks leads to these warnings about two instances of these symbols existing in the process.
This PR works around that problem by building
fake4swiftas a Mac app, which dynamically links the stdlib, and then copying the binary and embedded frameworks out of the.appand into the installation directory. This technique was first (AFAICT) popularized by Carthage (see Carthage/Carthage#16 or Carthage/Commandant#28), which has a similar setup.
