These are not real OSes, they are object file formats. There is a longstanding tradition of using them for embedded/freestanding programming, so it makes sense to parse them with `kernel=none`.
(I have a WIP future patch that systematizes parsing these non-OSes a bit more. That also opens the door to parsing a 5th component as LLVM can do.)
