Ok, I think I see what you're getting at. Instead of a multi-list
giving one result, you'd like to tick every box that kernel is
going run on, and have it spit out CONFIG_Mxxx for each of those

It's doable, and it keeps things like vendor kernels possible
(they just select all CPUs), it's probably quite a bit of work

The trickiest bit is getting the Makefile right to choose
the lowest-chosen-denominator in the list for its gcc options, and that's
probably not that hard, just a few extra ifdefs in an already ifdef heavy area.
Other than that, dealing with the cases like "this cpu has TSC" "this
doesn't" and "this has this bug" "this doesn't have this bug" need to be
done too, but thats again, just a few more ifdefs away..
