[testsuite] Fix gcc.dg/tree-prof/val-profiler-threads-1.c

The manual says that the type of the 2nd argument of pthread_join is void **.
Now gcc.dg/tree-prof/val-profiler-threads-1.c does this:

    int retval;
    for(t=0;t<NUM_THREADS;t++)
      pthread_join (threads[t], (void**)&retval);

which means a potential buffer overflow on LP64 targets in addition to an 
alignment issue if the target is strict-alignment, for example SPARC 64-bit.

Tested on SPARC64/Linux, applied on the mainline and 7 branch as obvious.

	passed to pthread_join.
