I don't try 3.0, but I've put an experimental patch
  http://dodo.nurs.or.jp/~kkojima/gnu-on-sh/gcc-cvs-010514.diff
  http://dodo.nurs.or.jp/~kkojima/gnu-on-sh/gcc-cvs-010515-2add.tar.gz
for 3.1 branch. It was relatively stable for 20000504 version
of 3.1 CVS tree. Unfortunately, now 3.1 can't even bootstrap.

You can configure gcc like as
  /xxx/gcc/configure --host=... --target=sh4-unknown-linux-gnu --enable-languages=c --enable-shared 
under this patch.
The option --enable-shared makes the shared libgcc which is new
in 3.x release. It needs some manual operations to make the shared
libgcc in the cross environment. The above patch uses the shared
libgcc libgcc_s.so as default. If you don't like it, specs file
must be modified.
