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_DECL([CONFIGNAME], VARNAME, VALUE, [DESCRIPTION], [IS-TAGGED?])
-# -------------------------------------------------------------------
-# CONFIGNAME is the name given to the value in the libtool script.
-# VARNAME is the (base) name used in the configure script.
-# VALUE may be 0, 1 or 2 for a computed quote escaped value based on

-# ------------------------------------
-# Quote a variable value, and forward it to `config.status' so that its

-# must have a single quote delimited value for this to work.
-
-
-
-# _LT_CONFIG_STATUS_DECLARATIONS
-# ------------------------------
-# We delimit libtool config variables with single quotes, so when
-# we write them to config.status, we have to be sure to quote all
-# embedded single quotes properly.  In configure, this macro expands
-# each variable declared with _LT_DECL (and _LT_TAGDECL) into:
-#
-#    <var>='`$ECHO "$<var>" | $SED "$delay_single_quote_subst"`'

-# -------------------
-# Send accumulated output to $CONFIG_STATUS.  Thanks to the lists of

-# to _LT_DECL, we can put quote escaped variables declarations
-# into `config.status', and then the shell code to quote escape them in

-
-# _LT_GENERATED_FILE_INIT(FILE, [COMMENT])
-# ------------------------------------
-# Generate a child script FILE with all initialization necessary to
-# reuse the environment learned by the parent script, and make the
-# file executable.  If COMMENT is supplied, it is inserted after the
-# `#!' sequence but before initialization text begins.  After this
-# macro, additional text can be appended to FILE to form the body of
-# the child script.  The macro ends with non-zero status if the
-# file could not be fully written (such as if the disk is full).
-# _LT_GENERATED_FILE_INIT

-# ---------
-# This macro allows early generation of the libtool script (before
-# AC_OUTPUT is called), incase it is used in configure for compilation
-# tests.
-# LT_OUTPUT
-
-
-# _LT_CONFIG(TAG)
-# ---------------
-# If TAG is the built-in tag, create an initial libtool script with a
-# default configuration from the untagged config vars.  Otherwise add code
-# to config.status for appending the configuration named by TAG from the
-# matching tagged config vars.

-
-# LT_SUPPORTED_TAG(TAG)
-# ---------------------
-# Trace this macro to discover what tags are supported by the libtool

-# lt_append(MACRO-NAME, STRING, [SEPARATOR])
-# ------------------------------------------
-# Redefine MACRO-NAME to hold its former content plus `SEPARATOR'`STRING'.
-# Note that neither SEPARATOR nor STRING are expanded; they are appended
-# to MACRO-NAME as is (leaving the expansion for when MACRO-NAME is invoked).
-# No SEPARATOR is output if MACRO-NAME was previously undefined (different
-# than defined and empty).
-#
-# This macro is needed until we can rely on Autoconf 2.62, since earlier
-# versions of m4sugar mistakenly expanded SEPARATOR but not STRING.

-# lt_combine(SEP, PREFIX-LIST, INFIX, SUFFIX1, [SUFFIX2...])
-# ----------------------------------------------------------
-# Produce a SEP delimited list of all paired combinations of elements of
-# PREFIX-LIST with SUFFIX1 through SUFFIXn.  Each element of the list
-# has the form PREFIXmINFIXSUFFIXn.
-# Needed until we can rely on m4_combine added in Autoconf 2.62.

-# lt_if_append_uniq(MACRO-NAME, VARNAME, [SEPARATOR], [UNIQ], [NOT-UNIQ])
-# -----------------------------------------------------------------------

-# by SEPARATOR if supplied) and expand UNIQ, else NOT-UNIQ.

-# 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.

-
-# 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

-# 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

-# 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.
