There's no way this is going to work, because $(notdir) is a Make function,
while $$k is only expanded when the shell is run by Make.  So when Make comes
to expand $(notdir), it sees $$k as its argument, and that expands to itself
(since it has no leading directories).

You want to use `basename $$k` instead.
