Fix the problem with ./buildconf not working right out of CVS.  The
general problem, is that we were using AC_CONFIG_AUX_DIR_DEFAULT, which
the autoconf source says shouldn't be called directly.  It should be
called using AC_REQUIRE, but I couldn't make that work.  So, since we know
exactly where the files that we are looking for are located, we'll just
point autoconf directly to them, and ignore all of the hoops.  :-)

I am not convinced the AC_CONFIG_AUX_DIR(.) call that I am using is
strictly necessary, but it doesn't cause any problems and it logically
makes sense.
