  <bridgehead renderas="sect4">Setting Host and Target</bridgehead>

  <para os="a">During the building of the cross-compile tools you will need to
  set a few variables that will be dependent on your particular needs.
  You will need to set the target triplet for the target architecture and CPU
  endianess. If you do not know what triplet or endianess you want,
  you can use the table at the bottom of this page as a reference. Set
  the command using the method listed below:</para>
