I was going to argue that I'd prefer the dependency to be on
BR2_PACKAGE_SYSTEMD instead, as I seemed to recall that's what we do
elsewhere.

So I grepped the code, and we have 22 instances where the dependencies
is on the package, and 20 where it is on the init system.

And in the end, it does make sense that this is done on the init sytem,
not the package, so I'm OK with the patch as is, and I would even argue
that the others should be changed (when they install unit files).

So:

(Yeah, I'm putting two tags at different places in the reply, just to
see how patchwork handles that. Niark! ;-) )
