cat << "USAGE_END"
Usage: fix_libtool_files.sh <old-gcc-version> [--oldarch <old-CHOST>]

    Where <old-gcc-version> is the version number of the
    previous gcc version.  For example, if you updated to
    gcc-3.2.1, and you had gcc-3.2 installed, run:

      # fix_libtool_files.sh 3.2

    If you updated to gcc-3.2.3, and the old CHOST was i586-pc-linux-gnu
    but you now have CHOST as i686-pc-linux-gnu, run:

      # fix_libtool_files.sh 3.2 --oldarch i586-pc-linux-gnu

    Note that if only the CHOST and not the version changed, you can run
    it with the current version and the '--oldarch <old-CHOST>' arguments,
    and it will do the expected:

      # fix_libtool_files.sh `gcc -dumpversion` --oldarch i586-pc-linux-gnu
