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.

for the DT_IA64_PLT_RESERVE dynamic table entry. When a shared object
does not have any PLT relocations, the linker apparently doesn't find
it necessary to actually reserve the space for the BOR (Bind On
Reference) entries as pointed to by the DTE. As a result, relocatable
data in the PLT was overwritten, causing some unexpected control flow
with annoyingly predictable outcome: coredump.
To reproduce:
	% echo 'int main() { return 0; }' > foo.c
	% cc -o foo foo.c -lxpg4

This relocation creates a function descriptor at the specified
address and is commonly used for C++ to create virtual function
tables.

Untested (testing request went unanswered), but sparc64 is not expected to
cause problems.  IA64 is not expected to cause problems but the patch was
slightly more complex so the possibility exists.
