Solving our bootstrap woes

This isn't a patch, it's just a new file to drop in the distribution as
m4/lt~obsolete.m4.  Ok, it needs adding to EXTRA_DIST as well, but
that's it.

I think the comment I've put in it explains how it works pretty well,
basically instead of whatever you've got in
/usr/share/aclocal/libtool.m4 turning up in your aclocal.m4, you get
this instead; which is harmless because the filename is asciibetically
after anything else in m4/ so the m4_ifdef just expand to [].

Okay to commit?

Have you ever, ever felt like this?
Had strange things happen?  Are you going round the twist?

# serial 1

# 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
# AU_DEFUNs it wants, but when m4 processes it, it doesn't do anything
# because those macros already exist.
# Anytime we withdraw an AC_DEFUN or AU_DEFUN, but still refer to it,
# remember to add it here.
