Change Tool Chain to GCC

To change the tool chain:

1. Import the Freescale ARM Compiler-based project into the workspace.
2. Create a new ARM GCC project using project wizard for later use.
   Note: You need to select GCC as ARM build tool in the Language and Build Tools Options page of the new project wizard.

3. Replace the *.cproject file of your project with the one from the new created GCC project. *.cproject file is located on the top level of your project folder. This file contains project settings, such as building tools to be used, various compiler options, and so on. With this trick, the building tool of your project has been changed to GCC.
