Hi,
  Like the .ctors array, __do_global_dtors_aux_fini_array_entry and
__frame_dummy_init_array_entry arrays need a specific alignment.  This
patch fixes those two arrays.  This patch fixes the bootstrap on
mips64-linux-gnu.

Bootstrapped on mips64-linux-gnu.
Bootstrapped and tested on x86-linux-gnu with no regressions.

Thanks,
Andrew Pinski

libgcc/ChangeLog:
* crtstuff.c (__do_global_dtors_aux_fini_array_entry): Align to the
size of func_ptr.
(__frame_dummy_init_array_entry): Likewise.
