title: issues trying to link project with libGoogleAnalitics.a for both armv6 and armv7
body: <p>I am trying to use Google Analytics iOS in my project, that supports iOS 4.0 onwards and looking at the Google Analytics resources <a href="https://developers.google.com/analytics/devguides/collection/ios/resources" rel="nofollow">page</a> I can see that version 1.5 they support architecture <strong>armv6</strong> and not <strong>armv7</strong>, and on 1.5.1 they added support to <strong>armv7</strong> but removed <strong>armv6</strong>.</p>
  
  <p>So if my project supports both architecture, and I try to use 1.5.1, I get an error on the linker:</p>
  
  <pre><code>ld: file is universal (3 slices) but does not contain a(n) armv6 slice: libGoogleAnalytics.a for architecture armv6
  </code></pre>
  
  <p>If I remove armv6 from my project supported architecture list, it compiles fine, works on device and simulator, but then later on I will get an error when submitting to apple store, the validator says:</p>
  
  <pre><code>at least one of the following architectures must be present: armv6.
  </code></pre>
  
  <p>Is there any way to create a version of the lib with both armv6 and armv7?</p>
