Building the latest version of mspgcc

To build the latest version of mspgcc (which supports the MSP430X extension) you can use the following script (which is a modified version of the one you can find on the old Contiki wiki).

#! /bin/sh
################################################################################
# This script builds mspgcc using gcc 4.7.2 as the basis.                      #
#                                                                              #
# This script is a modified version (by Daniele Alessandrelli) of the script   #
# created by Hossein Shafagh and hosted here:                                  #
# http://wiki.contiki-os.org/doku.php?id=msp430x                               #
#                                                                              #
# By default the compiler is installed in `~/mspgcc-4.7.2`. You can change     #
# this by modifying INSTALL_PREFIX.                                            #
#                                                                              # 
# IMPORTANT: This script creates a temporary directory `tmp` in the current    #
# path. Remember to remove it after the script execution.                      #
