build: Update libtool files to 2.4.3

* m4/libtool.m4: Update from libtool-2.4.3, with modifications.
2008-04-06  Bruno Haible  <bruno@clisp.org>
	* m4/libtool.m4 (LT_INIT): When setting LIBTOOL, use
	CONFIG_SHELL; don't assume that the Makefile.in will set SHELL
	to ${CONFIG_SHELL}.
* m4/ltoptions.m4: Likewise.
* m4/ltsuger.m4: Likewise.
* m4/ltversion.m4: Likewise.
* m4/lt~obsolete.m4: Likewise.
* build-aux/ltmain.sh: Likewise.

+## ------ ##
+## Usage. ##
+## ------ ##
+
+# This file is a library for parsing options in your shell scripts along
+# with assorted other useful supporting features that you can make use
+# of too.
+#
+# For the simplest scripts you might need only:
+#
+#   #!/bin/sh
+#   . relative/path/to/funclib.sh
+#   . relative/path/to/options-parser
+#   scriptversion=1.0
+#   func_options ${1+"$@"}
+#   eval set dummy "$func_options_result"; shift
+#   ...rest of your script...
+#
+# In order for the '--version' option to work, you will need to have a
+# suitably formatted comment like the one at the top of this file
+# starting with '# Written by ' and ending with '# warranty; '.
+#
+# For '-h' and '--help' to work, you will also need a one line
+# description of your script's purpose in a comment directly above the
+# '# Written by ' line, like the one at the top of this file.
+#
+# The default options also support '--debug', which will turn on shell
+# execution tracing (see the comment above debug_cmd below for another
+# use), and '--verbose' and the func_verbose function to allow your script
+# to display verbose messages only when your user has specified
+# '--verbose'.
+#
+# After sourcing this file, you can plug processing for additional
+# options by amending the variables from the 'Configuration' section
+# below, and following the instructions in the 'Option parsing'
+# section further down.
+
+## -------------- ##
+## Configuration. ##
+## -------------- ##

+# file so that they reflect the customisations you have added to the

+# '--help' output messages. You can embed shell variables for delayed

+# expanded when the contents are evaled.
