Which is a reasonable thing to have, if the function doesn't do anything on a given
architecture or configuration.

I admit being confoozled here - would leaving a function with an empty body be
a solution? Obviously it *would* be one, because the kernel currently does
that.

Feel free to try it and see what happens. :) (Make sure to try two different
configs, one that includes the version that has the non-empty body, and
one that tries to call the eliminated function without a body).
