 * Fragment of the ELF _init routine that invokes our dtor cleanup.
 *
 * We make the call by indirection, because in large programs the 
 * .fini and .init sections are not in range of the destination, and
 * we cannot allow the linker to insert a stub at the end of this
 * fragment of the _fini function.  Further, Itanium does not implement
 * the long branch instructions, and we do not wish every program to
 * trap to the kernel for emulation.
 *
 * Note that we require __do_global_ctors_aux to preserve the GP,
 * so that the next fragment in .fini gets the right value.
