For fat-lto-objects, I think it's more likely that the inclusion of the compiler data rather than the object code is triggering the extra warnings (since normal builds also include the object code but don't generate the warnings). It didn't generate any extra warnings when enabled on the coreboot tree so I think it should be safe to stick with the defaults.
