title: Error with cocoapods link_with after update to 1.0.0
body: <p>I have updated cocoapods today to 1.0.0 version. I got this string when I update the pods: </p>
  
  <p><code>[!] Invalid Podfile file: [!] The specification of link_with in the Podfile is now unsupported, please use target blocks instead..</code></p>
  
  <p>I have removed link_with in my podFile but I can't build the project because I have many Match-O-Linkers. Any one knows how should I fix this problem?</p>
  
  <p>This is my Podfile right now:</p>
  
  <pre><code>source 'https://github.com/CocoaPods/Specs.git'
  
  platform :ios, '8.0'
