I fear I have confused things with the configure.tgt fragment.  The main bulk of 
the patch was to make function return work for m68k-elf, which returns pointers 
in %d0. As that's an embedded target, it has no OS and so no OS sniffer.  As I 
understood gdb's internals, we should default to that ABI and use OS sniffers to 
set things up for OS ABIs that are different.

Is the patch ok without the configure.tgt fragment.  I can deal with uclinux 
separately.
