It looks like csky was created by copying & pasting the m68k port,
but m68k-specific stuff was left over related to target selection.
The makefile doesn't do anything with it, so punt it all to make
the file much simpler.

Now that the csky-specific logic ($DO) has been deleted, we can fold
it up a level easily enough.
