Thank you for submitting this patch.  I've not yet
had the time to perform a full review.  Maybe I'll
be able to do some testing over the week-end.

I noticed a few things:

 - In many places code is mis-indented or has
   minor white-space glitches;

 - You don't seem to consistently patch both MOTOROLA
   and !MOTOROLA paths.  Is this intentional?  AFAIK,
   there are no ColdFire targets using the MIT syntax,
   but we need to be consistent;

 - The patch isn't yet updated to the .opt conversion
   that occurred on mainline a few days ago.  Changing
   it should be trivial;

What are the changes you need to apply?

Would plain 68020 code run on v4e processor?  As far
as I can see, m68k-linux isn't a multilib target.
