Overriding linkcmds?

Thanks for your replies guys,

Sebastian - I'll see if I can figure out how to work that into my makefile.
I suppose I could try using the CFLAGS_FOR_TARGET again like I did with the
header include path....

Peter - I'm targeting a M68332 (specifically the mrm332 bsp). Ideally I'd
like a simple makefile switch I can turn on or off to target RAM or ROM,
but if it's too difficult I'll just cheat and rename my linker scripts
depending on where I want to load my code to.
