I think I know what the problem is. In a house, at the electrical
panel, the neutral wire is connected to the ground. Your tester maybe
assuming this and that is why it is not showing a ground connection.
Your generator probably has a floating output (neutral not connected to
the frame ground). Which is why the tested shows no ground. This will
not pose a problem when using the generator, it is still grounded, it's
just that the neutral is not connected to ground.

You're right about the floating neutral.

I found a couple of OSHA pages discussing portable generator grounding and
neutral bonding.

although it seems to contradict this one:
