I know I said that I'd do it but then I realized that it would probably
make more sense to add this macro when a non-x86 target is first
introduced (which I believe is patch 3 in your series). It's a one-line
change IIRC so it shouldn't be too disruptive to your series.

I should have mentioned it when I posted v3 of my patches, I apologize
for forgetting it.
