I thought that we were trying to reduce the amount of obj-y code
in order to make life easier for multiarch (because eventually
it's going to have to be compile-once anyway). And being obj-y
and having the whole of cpu.h available makes it very easy to
accidentally use target-specific defines and so on.

But Peter C has a better grasp of the current status of
multiarch than I do, so if he prefers using obj-y then
I'm happy to take his recommendation.
