Based on the strace, my guess would be that getrlimit() is what's
attempting to link to the dynamic library.  This is based on the
success of the uname() call and on what does NOT appear in the
subsequent trace output.  If getrlimit() does have this effect, it's
possible that getrusage() will as well.
