title: Building just one tool from Android source (AOSP)
body: <p>Currently I'm using the the <a href="https://aws.amazon.com/marketplace/pp/B00HZ3NSPE?ref=cns_srchrow" rel="nofollow">AOSP ROM Builder</a> image on Amazon AWS to build Android.<br>
  The point is, I'm only interested in the external tool <code>grxmlcompile</code> that is built for the host (linux) in the path: <code>aosp/out/host/linux-x86/bin</code><br>
  where the source is at <code>aosp/external/srec/tools/grxmlcompile</code></p>
  
  <p>I'm not very familiar with Linux and make files, hence my difficulty to get this going.</p>
  
  <p>I would like to copy the source (if needed the whole tree) and build just this tool on another linux machine.</p>
  
  <p>I can't find the make file I need to run to build just this part.</p>
  
  <p><strong>UPDATE:</strong>
  Looks like <code>make out/host/linux-x86/bin/grxmlcompile</code> would do the job. I would still like to be able to port only the needed parts of the source tree to the build machine</p>
