Wooden training axes cut trees in 34.x also, but if you play a version after the clothing requirement was introduced you are going to have to either farm or raise animals. There won't be enough leather from hunting to clothe everyone. Also, I am uncertain what the status is these days on fishing and hunting, but I don't think you can live on just those as food supplies. Nor might you have enough bone crafts to trade for food, leather, and cloth without animals domesticated. I guess you could allow the eating of sentients and live on dead goblins. Cannibal tribe! 
I keep all my dwarves clothed with whatever I pull off dead goblins. I just unforbid it, and they take it as needed. Whatever's left gets sold to the caravans. They stay clothed, and I get trade goods I didn't have to work for. It works out rather well.
also I have no idea if this would work, but.. small pits covered with retractable bridges, wait til the enemy is over them and throw one lever that opens them all? will need an engineer which isn't really tribal...unless it's like the temple from indiana jones. I'd consider those tribals engineers.
