* automake.in (handle_configure): Rename am__configure_deps

* automake.in (handle_configure): Rename am__configure_deps
as am__aclocal_m4_deps and include $(ACLOCAL_M4_SOURCES) and
$configure_ac.  Define am__configure_deps as am__aclocal_m4_deps
+ $(CONFIGURE_DEPENDENCIES) + $(ACLOCAL_M4).  Do not define
ACLOCAL_M4_DEPS while processing configure.am.
(make_paragraphs): Do not define %CONFIGURE_AC%, now unused.
(scan_aclocal_m4): Do not distribute aclocal.m4, this
is done from lib/am/configure.am.
* lib/am/configure.am (%MAKEFILE-IN%, DIST_COMMON,
$(top_srcdir)/configure, $(ACLOCAL_M4)): Simplify using
$(am__configure_deps) or $(am__aclocal_m4_deps).
* lib/am/remake-hdr.am ($(srcdir)/%CONFIG_HIN%): Likewise.
