[Gc] Minor Autotools-related fixes

Issue 1.  This fixes a warning from aclocal on newer Automake versions
(mine is 1.10.2):

   GC_VERSION_MINOR=`echo $PACKAGE_VERSION | sed 's/^[[^.]]*[[.]]\([[0-9]][[0-9]]*\).*$/\1/g'`

Issue 2.  The libtool.m4 file in the repo is outdated and also creates
warnings.  My suggestion is to remove this file from the repo, since
current version of libtoolize (mine is 1.5.26) does not install it into
the project directory.  That is, we assume that developers who want to
regenerate configure, have Libtool in addition to Automake and Autoconf.

The Autoconf-version selection in autogen.sh can then be updated:

diff --git a/autogen.sh b/autogen.sh
index afbfc55..b3156c9 100644
--- a/autogen.sh

+for v in 1.10 1.9 1.8 1.7; do
     if type -p &>/dev/null automake-$v; then

Alternatively, we can remove autogen.sh and suggest that developers
instead use "autoreconf -vif" which mostly does the same job, except
that we no longer try to pick certain versions.
