Umm, would this do?
makeoptions KERNEL=foo

That part isn't, it's passed in from the bootblocks and the loader.

This is with:

makeoptions KERNEL=vmunix
That should be as near to a replacement for 'config vmunix' as you can get.
There are a couple of places where the old name "kernel" is still hard coded
into the Makefiles, but they are much easier to fix now.
