title: Android NDK CPU Macros. ARMv7
body: <p>I found article that has following macros <code>__arm__</code>, <code>__i386__
  </code> </p>

  <p>It has solution for ARMv7 detection.</p>
  
  <p>But I would like detect that code was compiled for ARMv7 directly from CPP instead of using <code>Android.mk</code> to include different CPP files</p>
  
  <p>I am not looking for cpufeatures
  I am looking for target CPU for selected lib.</p>
