The nextafter(x, y) family of functions functions shall compute the next representable
floating-point value following x in the direction of y.
According to LSB, if the correct value is subnormal or underflows then ERANGE error code
shall be set.
But on the target machine the function sets error code EOK instead of ERANGE.
