Don't use a sub-`configure' for `guile-readline'.
* acinclude.m4 (GUILE_READLINE): New macro, based on the former `guile-readline/configure.ac'. * configure.ac: Remove `AC_CONFIG_SUBDIRS' invocation. Add `GUILE_READLINE' invocation. Produce files under `guile-readline'. * guile-readline/Makefile.am: Conditionalize the meat under `HAVE_READLINE'. (INCLUDES): Rename to... (AM_CPPFLAGS): this. Users updates. (AM_CFLAGS): New variable. (libguilereadline_v_@LIBGUILEREADLINE_MAJOR@_la_LIBADD): Add $(READLINE_LIBS). * guile-readline/readline.c: Include <config.h>. * guile-readline/configure.ac, guile-readline/autogen.sh: Remove.
