rrs: handle linking maintainership

Provide a mechanism set the maintainer for things like gcc-cross-<arch>
to the same as gcc. (We do have entries in the .inc file for these,
however they aren't useful as they don't match the recipe name when we
parse it, and due to the fact that RecipeMaintainer objects link
directly to Recipe objects, we can't handle entries that don't map to a
real recipe).
