I have accepted and applied this patch, but I did make one change.
Instead of having obj_elf_section_type() accept the init_array and
fini_array types I added it to ia64_elf_section_type().

If you feel that they ought to be supported generically then you will
need to update the documentation as well, plus test the change on a
couple of other systems as well.
