./configure --help indicates:

  --enable-external-tests Include the VTY/CTRL tests in make check
                          [default=no]
but

./configure ... --enable-external-tests
configure: WARNING: unrecognized options: --enable-external-tests

the name of the option seems to be --enable-ext-tests.
