title: CFBundleSupportedPlatforms issue
body: <p>On existing project that always built without issue on 10.10/Xcode 6 I am now getting this error with 10.11/Xcode 7:</p>
  
  <p>Couldn't find platform family in Info.plist CFBundleSupportedPlatforms or Mach-O LC_VERSION_MIN for myBinary</p>
  
  <p>I have 3 pre-complied binaries inside of my project.  They do have their own entitlements files and they are codesigned but they do not have their own Info.plist. I tried adding CFBundleSupportedPlatforms to the main Info.plist with the value MacOSX but it's not resolving the issue.  Any ideas?</p>
