Fix builtin detection conditionals.

* Correct detection of following cases.
  non-editline/readline, editline/non-readline, and editline/readline.
* If builtin editline has header files in include/editline, create
  include/readline/* symlinks.
* Fix PR pkg/48062 with above fixes. Confirmed on Ubuntu Linux/amd64 13.04.
