I think if I used the race, I'd set its automatic languages to halfling and goblin, with common as a bonus. The average golfling with have a 12 or higher int, so most of them will pick up common. It'd also allow for some interesting rp potential if the pc doesn't choose to pick up common. And it would be a deliberate choice, for I know of no one that'd play a 0 la race with an int bonus and NOT have a positive int modifier.
