title: building MobileVLC -> armc7 + ffmpeg issue
body: <p>I'm trying to build MobileVLC on OS X Lion, against iOS SDK 5.0. So far, no dice.</p>
  
  <p>Followed the given instructions, however, build stops and fails here: 
  [info] Building contrib for iOS in '/Users/shamil/Documents/MobileVLC/ImportedSources/vlc/contrib-builddir-ios-i686-apple-darwin10</p>
  
  <p>Current log:
  ./buildMobileVLC.sh -s
  [info] Preparing build dirs

  [info] Building contrib for iOS in '/Users/shamil/Documents/MobileVLC/ImportedSources/vlc/contrib-builddir-ios-i686-apple-darwin10'</p>
  
  <p>The error is given as follows:</p>
  
  <pre><code>make[1]: *** [.ffmpeg] Error 1
  make: *** [using-src] Error 2
  </code></pre>
  
  <p>/ImportedSources/vlc/contrib-builddir-ios-arm-apple-darwin10/build-src/ffmpeg/config.log tells me: </p>
  
  <pre><code>ld: warning: directory not found for option 'L/Users/shamil/Documents/MobileVLC/ImportedSources/vlc/contrib-ios-arm-apple-darwin10/lib'

  <p>I've bolded the one which I think is causing it to fail. Now - how do I fix THIS error?</p>
