[swift-dev] Building SwiftPM with Foundation

What you will need to do to make this work is to get the "fake toolchain" to look like how an actual toolchain looks on disk (e.g., libFoundation in the same relative position, in `<something>/../lib/swift/linux`), presumably using a symlink. The special rpath is what is causing the built swift-build (in this case the stage1 swift-build) to look in that directory for its libraries. If libFoundation.so is there, then that should suffice for it to be found and loaded.
