I can't reproduce this behaviour. ie. I can reference a function in the
linker script via an assignment, and have the function removed.  Are you
sure garbage collection is being done at all?  Note that if linking
against a shared lib, gc won't run.

I'm not sure why there is this restriction.  Catherine?
