That would break Debian which configures packages with `--host=sh4-linux-gnu`.

Also, I think I made the assumption that `sh3-linux-gnu` and  `sh4-linux-gnu` in packages like `libseccomp` when I added SuperH support because I wasn't aware that there were triplets where plain `sh` would default to big-endian.
