The "gentoo" way as near as I can see is via virtual packages, eg if 
there are three cron options then you install virtual/cron and various 
packages then provide that dependency.

With udev it's a little harder to fit it into that mould (actually same 
with all busybox utils) because basically bb can provide different 
things depending on config...

I think it's a hard problem to solve and a small number of affected 
users.  Probably as a workaround you should simply set package.provided 
to claim you have installed udev and then all the dependencies are 
effectively assumed to be solved.  Of course this will break down on 
some package that really does need proper udev, but it's probably 
acceptable?

A use flag is probably inappropriate because that's usually used to 
indicate whether you want that functionality compiled or removed from a 
given package

I guess there must be some -arm overlay that you can base from and 
contribute to?  Anyone?

Good luck
