title: How to determine build architecture (32bit / 64bit) with ant?
body: <p>We have inherited an ant build file but now need to deploy to both 32bit and 64bit systems.</p>
  
  <p>The non-Java bits are done with GNUMakefiles where we just call "uname" to get the info.  Is there a similar or even easier way to mimic this with ant?</p>
