Hm.  I've re-checked the documentation and it's actually quite clear about
this: if the name is a builtin function then that function is invoked
instead of any variable by that name.  Make is behaving as the docs require.

I'm not sure this makes sense, however.  Offhand it seems to me that call
should prefer user-defined functions.

We'd need to think carefully about this before making that change however.
