bfd/elfxx-ia64.c patch

[Steve Ellcey]

I think elfxx-ia64.c may be unique in that it has two specialized
vectors defined at the end of it, one for AIX and one for HP-UX.  This
results in the necessity of "resetting" any macros that are defined to
AIX specific functions back to their defaults before defining the HP-UX
vector.  Without this the HP-UX vector could call some AIX functions
which is not what is desired.

I am not entirely happy with the way I am doing this but I couldn't find
a cleaner way to reset them.  I tried "saving" the old value of
elf_backend_add_symbol_hook and bfd_elfNN_bfd_link_add_symbols in
another macro before AIX reset them but that did not work.

Can someone review this and, if it is OK, check it in.  I have no write
permission but do have a copyright assignment on file.
