Create a new project. The CordovaLib build rules do not include the arm64 target, but the project ones do, and the "build active architecture only" flag is set to true. So when building for an iphone5S, it fails to link. Need to either update the project or CordovaLib build rules to make their architectures match, or change the build flag. It's not a great experience when building the "Hello World" or initial app.
