Fix a mod_ssl build problem on OS/390. 

This is admittedly rather ugly code to come up with a unique 4-byte
identifier for the thread.  Since our threads are pthreads and a pthread
maps 1:1 to a TCB, the address of the TCB is sufficient.   Yes, every
TCB sees a different piece of real storage mapped to the first page,
so the code does make sense.
