Add a stub version of getpublickey(), in order to eliminate an

undefined symbol referenced from libc.  Without the stub, it is
impossible to execute any program using the shared library if
LD_BIND_NOW=1 is in the environment.  The stub always returns
failure, but it can be overridden outside the library when necessary.

I don't know whether this is the "correct" fix, but it is intolerable
to have any undefined symbols referenced from libc.
