I'm not sure if that patch is all that is needed. You may need to
change more things like TARGET_WORDS_BIGENDIAN in the configure
script.

I have not tested sh in big endian mode yet, so I'm not sure what
issues you may run into. I have however noticed that regardless of
endian target libraries may feel the need of loading host files such
as /etc/ld.so.cache which in turn may lead to some serious confusion.

Maybe the path remapping engine in scratchbox2 solves this issue?

The release sbox2-1.99.0.19 does not support SH out of the box, but
the latest git version should be ok.

Good luck!
