sim: switch to AC_CONFIG_MACRO_DIRS

Rather than hand maintain m4 includes in various autotool files,
use AC_CONFIG_MACRO_DIRS to declare the relevant search paths.
This simplifies the code, makes it more robust, and cleans out
unused logic from configure.

-
-
-
-# _LT_CONFIG_STATUS_DECLARATIONS
-# ------------------------------
-# We delimit libtool config variables with single quotes, so when

-# ------------------------------------
-# Generate a child script FILE with all initialization necessary to

-
-# _LT_CONFIG(TAG)
-# ---------------
-# If TAG is the built-in tag, create an initial libtool script with a

-# serial 4 lt~obsolete.m4
-
-# These exist entirely to fool aclocal when bootstrapping libtool.
-#
-# In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN)
-# which have later been changed to m4_define as they aren't part of the
-# exported API, or moved to Autoconf or Automake where they belong.
-#
-# The trouble is, aclocal is a bit thick.  It'll see the old AC_DEFUN
-# in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
-# using a macro with the same name in our local m4/libtool.m4 it'll
-# pull the old libtool.m4 in (it doesn't see our shiny new m4_define
-# and doesn't know about Autoconf macros at all.)
-#
-# So we provide this file, which has a silly filename so it's always
-# included after everything else.  This provides aclocal with the
-# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
-# because those macros already exist, or will be overwritten later.
-# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6.
-#
-# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.
-# Yes, that means every name once taken will need to remain here until
-# we give up compatibility with versions before 1.7, at which point
-# we need to keep only those names which we still refer to.
-
-# This is to help aclocal find these macros, as it can't see m4_define.

-# ZW_PROG_COMPILER_DEPENDENCIES
-# -----------------------------
-# Variant of _AM_DEPENDENCIES which just does the dependency probe and
-# sets fooDEPMODE accordingly.  Cache-variable compatible with
-# original; not side-effect compatible.  As the users of this macro
-# may require accurate dependencies for correct builds, it does *not*
-# honor --disable-dependency-checking, and failure to detect a usable
-# method is an error.  depcomp is assumed to be located in
-# $ac_aux_dir.
-#
-# FIXME: Should use the Autoconf 2.5x language-selection mechanism.

-
-
-# AM_SET_DEPDIR
-# -------------
-# Choose a directory name for dependency files.
-
-
-# ZW_CREATE_DEPDIR
-# ----------------
-# As AM_SET_DEPDIR, but also create the directory at config.status time.

-# intl sister-directory configuration rules.
-#
-
-# The idea behind this macro is that there's no need to repeat all the
-# autoconf probes done by the intl directory - it's already done them
-# for us.  In fact, there's no need even to look at the cache for the
-# answers.  All we need to do is nab a few pieces of information.
-# The intl directory is set up to make this easy, by generating a
-# small file which can be sourced as a shell script; then we produce
-# the necessary substitutions and definitions for this directory.

-# ACX_CHECK_INSTALLED_TARGET_TOOL(VAR, PROG)
-# Searching for installed target binutils.  We need to take extra care,
-# else we may find the wrong assembler, linker, etc., and lose.
-#
-# First try --with-build-time-tools, if specified.
-#
-# For build != host, we ask the installed GCC for the name of the tool it
-# uses, and accept it if it is an absolute path.  This is because the
-# only good choice for a compiler is the same GCC version that is being
-# installed (or we couldn't make target libraries), and we assume that
-# on the host system we'll have not only the same GCC version, but also
-# the same binutils version.
-#
-# For build == host, search the same directories that the installed
-# compiler will search.  We used to do this for the assembler, linker,
-# and nm only; for simplicity of configuration, however, we extend this
-# criterion to tools (such as ar and ranlib) that are never invoked by
-# the compiler, to avoid mismatches.
-#
-# Also note we have to check MD_EXEC_PREFIX before checking the user's path
-# if build == target.  This makes the most sense only when bootstrapping,
-# but we also do so when build != host.  In this case, we hope that the
-# build and host systems will have similar contents of MD_EXEC_PREFIX.
-#
-# If we do not find a suitable binary, then try the user's path.

-# AC_PROG_CPP_WERROR
-# Used for autoconf 2.5x to force AC_PREPROC_IFELSE to reject code which
-# triggers warnings from the preprocessor.  Will be in autoconf 2.58.
-# For now, using this also overrides header checks to use only the
-# preprocessor (matches 2.13 behavior; matching 2.58's behavior is a
-# bit harder from here).
-# Eventually autoconf will default to checking headers with the compiler
-# instead, and we'll have to do this differently.
-
-# AC_PROG_CPP_WERROR
-
-# Test for GNAT.
-# We require the gnatbind & gnatmake programs, as well as a compiler driver
-# that understands Ada.  We use the user's CC setting, already found, and
-# possibly add $1 to the command-line parameters.
-#
-# Sets the shell variable have_gnat to yes or no as appropriate, and
-# substitutes GNATBIND and GNATMAKE.
