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.
