    or1k: Correct longjmp return value
    
    Invert equality check instruction to correct the return value handling
    in longjmp.
    
    The return value should be the value of the second argument to longjmp,
    unless the argument value was 0 in which case it should be 1.
    
    Previously, longjmp would set return value 1 if the second argument was
    non-zero, and 0 if it was 0, which was incorrect.
