ddd-3.2.1 build readline when you do not want it

[Adam J. Richter]

        If you configure ddd-3.2.1 without "--with-readline", it
builds its internal version.  This is because have_readline in
configure.in is initially false, and, in the absense of "--with-readline",
it is never changed.  There are a variety of ways to fix this.
Here is a one line patch that is simple, although perhaps not the
most proper (better would be to change the logic to only
build readline if something like "$with_readline && ! $have_readline"
were true.
