title: how to add custom tool chain to eclipse CDT
body: <p>I have got a custom tool chain based on gnu arm. I have downloaded eclipse IDE with CDT. I would like to know how to add my tool chain with the eclipse. It has got a generic tool chain namely Linux GCC. Apart from that there is nothing. I would like to add mine.
  I am not finding any set up window that helps me in that.
  Thank you.</p>
