At that point, you need libc + kernel headers for sh-linux target.
They can be fed from somewhere.  But wait, the story is not easy.
See

  http://sources.redhat.com/ml/crossgcc/2002-05/msg00094.html

and the thread starting from

  http://gcc.gnu.org/ml/gcc/2003-06/msg01472.html

That's why guys including me strongly recommend Dan's crosstool.
