    fix runtests to use pthreads support for various Unix platforms
    
    The runtests program currently fails with
    
        Specific platform thread support not detected
    
    on HP-UX, AIX and other Unix systems which do not match the conditional
    
        #if defined(linux) || defined(__sun) || defined(__APPLE_CC__)
    
    It is silly to try to enumerate all systems which use pthreads in a conditional
    like this. I am attaching a patch (against git master) that rewrites the cpp
    conditional structure so that pthreads is used if HAVE_PTHREAD_H is defined,
    and moves that section of code down below the Win32 and BeOS cases so that
    native thread libraries are used preferentially in those two cases.
