Yes, that was the idea.  No need for official space, but admittedly there
would be a problem if all the 8 bits became officially used.  Like I said,
I was just toying with ideas.  There are a number of other possibilities
available.  eg. Add another field to struct elf_obj_tdata, used in much
the same manner as local_got.
