system inc and dynamic linker change

[Aseem Rastogi]

i am not sure about existing application but for a new program 
-Wl,--dynamic-linker option works. i successfully did it for simple 
hello world kind of programs but when i created shared libraries using 
this option, it didn;t work and they seemed to be linked to default linker.

try compiling gcc with this option to escape --dynamic-linker everytime.

regards,
aseem.

The end is always good. If it's not good, it's not the end.
