Installing the native avit gcc toolchain on the avit:

1) Copy the avit-gcc-4.2.3.tar.gz file to the avit cf memory card
   (/tmp/cf) using whatever method you like. 

2) Use tar to extract the file contents to the /tmp/cf/ directory. 
   "tar -xvzf avit-gcc-4.2.3.tar.gz -C /tmp/cf/"

3) Mount /tmp/cf/opt as /opt. This is important so that the toolchain can
   find its respective components, libraries and include files. Consider
   adding the following command to the autorun script. 

   "mount /tmp/cf/opt/ /opt"

4) The /opt/usr/bin directory has been added to the default login profile. 
   (Note: autorun does not use the login profile so you will need to 
    update the search path accordingly - "export PATH=$PATH:/opt/usr/bin")
