I have never heard any of those Buddhist philosophies speaking of truth like you seem to imply. They don't mean truth in the way Aristotle thinks about it.
Philosophically they aren't concerned with truth. They are concerned with the ultimate truth which can't be reached through theorizing. They have no problem with conventional western based truth it's just not the bedrock.
Or put another way. Buddhist would say you can't know the truth but you can be it.
