This macro returns the address of the DTV of the current thread.
This normally is done using the thread register which points
to the dtv or the TCB (from which the DTV can found).
+
+
+ THREAD_GSCOPE_IN_TCB
+
+ This should be set to 1 if the global scope flag is stored within the TCB.
+ When set to 0, GL(_dl_thread_gscope_count) will be defined to store it.
