To be more precise:
  - I did not specify --enable-cxx-flags
  - $enable_cxx_flags has the value "none" at this point, by the test
    -n.

Look at the expansion in configure:

if test "${enable_cxx_flags+set}" = set; then
  enableval="$enable_cxx_flags"
  case "x$enable_cxx_flags" in
  xyes)
    { echo "configure: error: --enable-cxx-flags needs compiler flags as arguments" 1>&2; exit 1; } ;;
  xno | xnone | x)
    enable_cxx_flags='' ;;
  *)
    enable_cxx_flags="$enableval" ;;
esac
else
  enable_cxx_flags=none
fi
