Laziness, the targets support different subsets of the math builtins so at a high level it makes sense to split them. The rest of the math library doesn't use built-ins so there's no point making some common `builtin/` directory I wouldn't think. The long term goal is to collapse a lot of this so I wasn't overly concerned with redundancy for now.
