top-level: Introduce targetPackages and a "double link fold"
Each bootstrapping stage ought to just depend on the previous stage, but poorly-written compilers break this elegence. This provides an easy-enough way to depend on the next stage: targetPackages. PLEASE DO NOT USE IT UNLESS YOU MUST! I'm hoping someday in a pleasant future I can revert this commit :)
