[PATCH][Cilkplus] Patch to fix unused variable

[Iyer, Balaji V]

Hello Everyone,
    This patch is for the Cilkplus branch affecting both C and C++ compilers. 
This patch will fix an unused variable warning in collect2.c by enclosing the 
variable inside #ifdef TARGET_AIX_VERSION.

Thanks,

Balaji V. Iyer.

        * opts.c: Removed the CILKPLUS_IMPLEMENTED macro and the #ifdef and
        #ifndefs that uses this macro.
+       * collect2.c (main): Enclosed object_nbr declaration inside a
