Retcon. I'd believe a game released about 3 years ago over a game released over 20 years ago. The new information overtakes the old. Plus, that information was never in TLoZ. It was in the TLoZ instruction manual. The Minish building them was an in-game explaination. I don't know if you share the same view, but if the information from a game's manual that is over 20 years old conflicts with in-game information from a game released about 3 years ago, the newer, in-game information wins hand down. That is just my opinion, though.
