rust-llvm: fix up generated packages

Avoid issues with non-native builds by splitting up the packages a
little closer to how they should be while still leaving the main package
containing everything Rust uses. This makes it possible to build
rust-llvm for the target, hopefully improving issue meta-rust#81.
