Fix for ia64/48024 - ensure function pointer equality across elf objects.
Fix for ia64/48024 - ensure function pointer equality across elf
objects.

Programs such as sshd depend on two pointers to the same function being
equal in a given process. However, the current ia64 implementation
ensures that they're equal when both the pointers are instantiated in
the same ELF object. The attached patch ensures that they're equal
irrespective of where they're instantiated.
