  This is probably doable, but in my experience with cross-compilation, you
  do not just generate code, you effectively generate a module that works
  with a much larger system.  To make this _really_ work, you have to have
  intimate knowledge of the target system.  Since the compiler is often the
  first thing you build on a new system in order to build the other tools
  you want to use there, my thinking is that you save a lot of time using a
  pre-existing compiler and like tool, particularly to ensure that you get
  the linking information right for that particular environment, what with
  all the shared library dependencies and whatnot.

  In a fight for something, the fight is a loss, victory merely relief.
