title: Lazarus cross compile from 32bit to 64bit
body: <p>I know I can cross compile from 64bit to 32bit in Lazarus:

  <p>But I need to compile 64bit from a 32bit OS install. My CPU is 64bit but I never installed 64bit Ubuntu when I did my OS install.</p>
  
  <p>I want to try to keep away from installing a virtualbox with 64bit Ubuntu as it's a lot of time required and my Lazarus is very customized. So I'm looking for some way to compile into 64bit from my 32bit Linux OS.</p>
