Actually, I don't feel strongly about this patch.  It's the first
version that worked.

I checked Linux sources (arch/powerpc/kernel/vmlinux.lds.S) and I see
that .sbss is put to the .bss section in front of .bss itself.  Perhaps
that's what we should be doing in OpenBIOS.

This patch works too:

+	*(.sbss.*)
 	*(.bss)
