Yes, using ld to link directly is rather tricky.  We always recommend 
that users use gcc to link, instead of ld, because gcc knows what 
options to pass for libraries and such.  You can still pass options to 
the linker with "-Wl"; for example:

   gcc -Wl,-map,map.txt file.o -o program.exe

passes along the "-map" option to the linker.

Is there a reason that you need to use "ld"?

It's possible that something is requiring some symbol defined in 
coldfire-vector.o (from libcs3coldfire.a) and therefore the linker is 
pulling that in, even though you've already got a definition.  You could 
probably see if that's the case by looking at the mapfile.  (See options 
above.)
