Currently, the only FFI function used during build (without-x11)
is |remove_directory| in |erase_lib|, and there has a Lisp fallback.
So the autotools variable "fricas_has_directory_operations"
means we have those C functions, while Lisp symbol
:fricas_has_remove_directory means we can use them.
This is not true for CLISP built without FFI.
Following patch fixes that.
An additional advantage: it is now easier to port FriCAS to
another Lisp. We can add the missing #+ Lisp functions first,
and add the FFI functions later.
