If there is no libtermcap all the readline tests failed.

This inappropriately disabled some capabilities which exist.

Now test for readline in -lreadline, if not found there, try it
in -ltermcap only if not in -lreadline.  If both libraries are
required, there will need to be more work, but I'm not sure
under what conditions both libraries would be required.
