sh: Don't export __{s,u}divsi3_i4i from SH-2 libgcc.

rsk7203_defconfig fails to build with the following error:

<--  snip  -->

...
  LD      .tmp_vmlinux1
arch/sh/kernel/built-in.o:(__ksymtab+0xb8): undefined reference to `__udivsi3_i4i'
arch/sh/kernel/built-in.o:(__ksymtab+0xc8): undefined reference to `__sdivsi3_i4i'
make[1]: *** [.tmp_vmlinux1] Error 1

<--  snip  -->

That worked with 2.6.26, and these are far less undefined references
than in the cases where libgcc was missing.

[ These symbols are not defined on SH-2 versions of libgcc, so we have to
  special case the export there. - Paul ]
