 I just noticed now: you added the patch dependencies to show-depends, but not
to -all-source, -all-external-deps and -all-legal-info. Isn't that wrong? Of
course, at the moment it makes no difference because it's only used for linux
extension packages and in that case the linux package is always selected anyway
so it'll end up in $(TARGETS) and get printed that way. But it just feels a bit
inconsistent.
