Commit Message

  When using abicompat, if the --redundant option and --no-redundant
option are used at the same time, no error will be prompted, the
actual option will prevail.

This patch provides a error to notify the user that error.

        * tools/abicompat.cc (main): Notify the user when --redundant
        and --no-redundant are used at the same time
