  <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. You can do this by running the same command as above, just
  running it on the target machine. If you can't run the command on the
  target machine, you can use the table at the bottom of this page. Set
  the command using the method listed below:</para>

<screen os="d"><userinput>export CLFS_TARGET="{target triplet}"</userinput></screen>

  <para os="e">Now we will add this to <filename>~/.bashrc</filename>, just in
  case you have to exit and restart building later:</para>

<screen os="f"><userinput>echo export CLFS_TARGET=\""${CLFS_TARGET}\"" &gt;&gt; ~/.bashrc</userinput></screen>
