This patch adds the --with-system-readline option to the gdb configure
script. OK?
Andreas.

* configure.ac: Accept --with-system-readline.
(READLINE, READLINE_DEPS, READLINE_CFLAGS): Define and substitute.
* configure: Regenerate.
* Makefile.in (READLINE, READLINE_DEPS, READLINE_CFLAGS): Use
substituted values.
(CDEPS): Use $(READLINE_DEPS) instead of $(READLINE).
