* Fragment of the ELF _fini 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_dtors_aux to preserve the GP,
* so that the next fragment in .fini gets the right value.
