Changing your settings to easy won't make any difference. When the game is running, changing the game speed also won't make a difference, only when the game is closed. The only sure-fire way to speed up the building is to put more than one builder to work. If you can't afford another villager to put on building you don't need the hut in a hurry as you can't afford to increase the size of the tribe yet, anyway.
