    [TRAFODION-2314] MXOSRVR sometimes exit abnormally with NAMutex assert

    The test suite fails becuase pthread_mutex_unlock returns EPERM error
    
    pthread_mutex_lock and pthread_mutex_unlock always return success when
    a program is not linked with -lpthread option. It is linked this way
    when a multi-threaded program is run in single thread mode to avoid the
    overhead of locking.
    
    The mxosrvr program is now linked with -lpthread. However, it is not
    clear how and why it would fix the EPERM error returned from
    pthread_mutex_unlock API. But it is good to ensure that mxosrvr .sos and
    the binaries are compiled with -lpthread.
    
    Will revisit this issue if the problem persists.
