When linking in --make we check the modification time of the executable against the modification time of the object files, and only re-link if any object file is newer. However, we should also check the modification times of packages, since the recompilation checker also tracks dependencies in packages. In a GHC build this means that if you recompile stage2 and don't manage to change any fingerpints, we won't recompile Main but we'll still re-link it.
