On a 48k Apple II, the BLTU2 call throws an error, even when there is nothing to copy in the LC segment. Add an alternative LC copy, based on memcpy, to an extra file that the user can link in as with iobuf-0800. This memcpy-based version allows our programs to run on Integer ROM apple2. It costs 21 bytes in binary size, plus memcpy (60 bytes in binary size + RAM use) if it wasn't already linked in.
