The problem here is different.

You built a separate compiler (or whole toolchain) especially for sh4eb.

However, this bug report says about sh4-linux-gnu-gcc, not sh4eb-*.
As documented, this compiler has -mb option, to produce big-endian code.
And this option does not work, with very minor omission which prevents
it from working.  Everything else seems to be here, just filling small
gap will let things work, without the need to build separate toolchain
especially for sh4beb.

Maybe I should retitle this bug report somehow to make this clear.

Thanks,
