Most portable generators come with a neutral / ground bond jumper inside the generator panel
I'm not so sure that most generators come with a N/G bond actually. My 6K watt Sportsman doesn't, and when I brought my testing meter to Lowe's many months ago just out of curiosity, a grand total of zero floor demo models had a N/G bond.
I'm not sure if the manufacturers assume that homeowners will have the bond in their panel (as that's what most homeowners buy generators for) or some other reason, but I'm inclined to think that most generators available in the hardware stores do not have a N/G bond from the factory.
Some manufacturers will provide a jumper and instructions on how to connect it. It seems, more often than not, if the generator manufacturer provides GFCI protection on, at least, the 120V 15-20A receptacles, there is either a bond connected at the factory or a factory supplied provision for it. That NOT to say there aren't some without GFCI protection that are bonded or some with GFCI protection lack a bond and/or a provision for it.
A floating system is, in many cases, considerably safer when using portable cord and plug connected equipment since there isn't a return path from either circuit conductor to ground. Once the neutral is bonded to ground, the potential for a ground-fault (faulty cords, tools etc) exists even if the genny is only sitting on the damp ground without connection to a grounding electrode. The danger becomes the same as using a non-GFCI protected receptacle powered by the utility.
Looking at some of the suggestions made on Internet forums seems to suggest that many don't quite understand that electricity from a generator will kill someone just as dead as electricity provided by the POCO. Electricity+inexperience+tiredness+darkness+dampness can equal a death statistic.--
