Compiling Rust with GCC: an update

When i was at Wind River in the late 90s SuperH was an alive and well dev board type that people were actively developing on. I'm sure the arch made its way into various devices. I have no idea which if them are potentially still alive, of course, but I suspect it's not a trivial amount.

At the same time, it was dwarfed by powerpc, x86, mips, arm, and even sparc.
