Don't do that.

I think it would be much better to instead do something like

obj-y += mmconfig_$(CONFIG_WORD_SIZE).o

to make it clear when we have a file that is conceptually the same, but
has different implementations.

That also makes the unification (assuming/hoping it gets done) of such
files much cleaner - you just merge them, and the obj-y line can just drop
the $(CONFIG_WORD_SIZE) thing. Very logical.

.. the above approach also gets rid of any link order problems.
