I guess Thomas doesn't remember :-) I believe the main problem is in the non-package targets, e.g. target-generic-hostname. They are just added to TARGETS without further dependencies. Same is true for the toolchain: it is just prepended to TARGETS. Changing that requires careful thinking about how the TARGETS work, and is not easy to verify because there are a lot of corner cases involved.
