When you build the final upgrade required to upgrade a tribe into a castle, you get a notification at the top of the screen telling you that you can upgrade a holding (This is for characters who are feudal, with tribal holdings, and I'm pretty sure it will NOT work when first upgrading to feudalism)
if you keep the buildings screen for the tribal holding open, then click the notification at the top, and upgrade to a castle, all the buildings in that tribal holding will disappear, and you can build them again, with their bonuses being applied to the castle! see screenshot below, of a castle with its fort level being improved by an earth hillfort
I believe, that as long as you keep that tribal window open, you could theoretically build all tribal buildings, but there is no way to re-open that window once its closed. this is also why I think it's impossible to do this when first upgrading to feudalism, opening the intrigue menu closes the building window.
