I'm suggesting that Debian use `--host=sh4el-linux-gnu` (or similar), which would work with both compilers and is unambiguous. As far as I can tell from a quick GCC build, the GNU toolchain has no problems with that triple.

(Of course, I'm not expecting the whole distro -- multiarch tuple and all -- to migrate to that. That'd be a lot of pain for questionable benefit.)
