I think this is a good point, but I think you're mostly talking about building rather than porting. It's way more likely you'll be able to port something from a popular architecture to an obscure one in C because the lingua franca is C, and shipping an architecture generally means shipping C compiler support for it. I would guess this will slowly change as LLVM gets more backends, but that's pretty hand-wavy. The other option is we move more towards platform monoculture, which is probably more likely? Not sure.
