Here you should be able to use the macro EXCEPTION_TABLE from
vmlinux.lds.h.
I cannot see why the ifdef for not NON-MMU case is needed,
but if it is needed the macro is not good...

Because you can not mention the same input section in two different
places and end up with predictable output from the linker.

We discard the __ex_table for noMMU, but I think the start/stop
symbols are still referenced somewhere.  Dunno, I don't have much to
do with noMMU ARM, and the only platform I'd be interested in never
got merged.

I was thinking, perhaps we can ifdef out the exception fixup sections in
the places where they're added? Then we can just use the EXCEPTION_TABLE
macro from vmlinux.lds.h knowing that there are no __ex_table sections
in the input object files?
