title: unknown option character `f' in: -fno-objc-arc
body: <p>I'm on xcode 4.3.2 and I'm compiling zmqobj <a href="https://github.com/jeremy-w/objc-zmq.git" rel="nofollow">https://github.com/jeremy-w/objc-zmq.git</a>. The original targets included in the project are for os x, but I'm trying to add a new target for ios.</p>
  
  <p>For the new target it's giving me ARC complaints (because the code is non-ARC). However when compiling for the original os x target it doesn't give me these warnings.</p>
  
  <p>Adding the -fno-objc-arc gives me:</p>
  
  <pre><code>/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/libtool: unknown option character `f' in: -fno-objc-arc
  </code></pre>
  
  <p>I must be setting the target wrong but I don't know what is wrong with it. Help appreciated, thank you.</p>
  
  <p>Edit:</p>
  
  <p>I'm adding the flag in the target->build phases->compiled sources. I have done this before for projects I created on my own and it works. But for this project it's not recognizing that.</p>
