Hello Ian,
Thanks for the response.
I guess, your right. The issue related to target specific implementation only.
I am able to calculate the offset from the GOT table to a symbol in data 
section. But its not enough. The GOT should be filled with all global symbols, 
which I am missing now.

Thanks for your comment.

Thanks
Swami
