title: MODULE.TARGET.SHARED_LIBRARIES.libjpeg already defined error
body: <p>I am trying to build kernel for AOSP 4.4.2 for a device. When I compile the kernel I get </p>
  
  <pre><code>build/core/base_rules.mk:134: *** vendor/google/libs: 
  MODULE.TARGET.SHARED_LIBRARIES.libjpeg already defined by external/jpeg.  Stop.
  </code></pre>
  
  <p>I understand that the shared variable libjpeg is already defined and I need to remove one of them. Is that correct? </p>
  
  <p>I tried looking in external/jpeg folder and I am not sure which file I have to look into. Could some one please tell me how to deal with this situation.</p>
