Adds a check for the minimum mainline GCC version for FORTIFY_SOURCE
support and enables -D_FORTIFY_SOURCE=2 by default when building with
--enable-debug.

Unfortunately this patch is hard to split up into smaller chunks. Our build
system and the associated automake/autoconf/libtool macros has been left
untouched for a while, and could use a refresher.
* Upgrade ltmain.sh to the latest version
* Move away from a huge acinclude.m4 directory to using individual files in
the m4/ subdirectory, suggested by upstream automake documentation
* Update all macros to their latest available version
* Adjust Makefile.am and autogen.sh to accommodate m4/ subdirectory

We only use it with --enable-debug, so we might as well go all out and try
to find any attempt of stack smashing.

This follows the removal patch previously used for GCC & F77 macros. If we
don't use it, dump it so we can speed up configure time.

We don't use Fortran or Java code in our project, so no need to waste time
looking for this stuff. This gives a noticeable speedup to running the
./configure program as well.

Hopefully these new autoconf macros, with a little magic, will allow us to
compile with any compiler and still choose the options we have available
to us.
Tested locally with gcc 4.2.2 and gcc 3.4.6; the latter doesn't support two
of the items we previously had hardcoded in our CFLAGS.

It looks like some of the newer libtool m4 files offer improved support
for the Darwin platform and possibly BSD, so bump our files to these new
versions.

* Greatly simplify and de-obfuscate the autogen and autoclean code.
* Add a bunch of the autotools required files to the repository. This
will give us consistency (a novel idea) across all builds, and allow
for much more recent versions of config.guess and config.sub to be used.
