use $(LN_S) and $(RM) for installing and uninstalling symlinks to deprecated
tool names.

Also add a comment to the Makefile.am based on Ralph's observation that:
  According to the docs, AC_PROG_LN_S will substitute 'ln' or 'cp -p' if
  the system doesn't support 'ln -s'. So that makes it more likely for
  the install to work, but may break the 'was this me?' test in the
  uninstall target.
