__kmpc_global_num_threads bug

Runtimes OpenMP
1

Though not used, the __kmpc_global_num_threads, based on the comments for it, returns the value of the wrong variable. Below is a patch for a fix, which I think I did it right.

Where is the official link for submitting bugs and patches?

Thanks
Yonghong
