I think an improvement on the symlink solution would be to incorporate
Chuck Wilson's suggestion of installing the newer autotools into a
separate prefix.  Then, the wrapper script could check AC_PREREQ, and
based on what it finds, could directly 'exec' the correct version of
automake or autoconf.  If necessary, the wrapper script could also
modify PATH for the automake/autoconf child processes.
