I went digging through a lot of ColdFire documentation to see if
there were ever any that needed it, and apparently it's been in there
since the beginning.

It did occur to me that perhaps someone wanted to support tne
intersection of all 68k family CPUs, so that meant only MULU.W
and ADD.L.  But I can't see a gcc option to ask for that.

My guess is that someone added the support just to get it through the
assembler, without thinking about not compiling it at all for coldfire
configurations.
