commit 457d33de89939ffaa523c2a6377ed7d1506ce255

    Handle empty event name spec gracefully for PPC
    
    During testing Michael Petlan found that the giving an empty event
    name in the event spec to operf on PPC machines would cause operf
    crash.  Running the following following command would demonstrate
    this problem:
    
      operf -e : /bin/ls
    
    The problem was traced to event_name in _handle_powerpc_event_spec
    function having a length of 0.  The strncmp using event_name in
    _handle_powerpc_event_spec would indicate a match and cause strncpy to
    be called to copy zero bytes. The zero length strncpy would crash
    operf.  Added a check to make ensure that the string is non-zero
    length.
