I removed it.  See:
https://gitlab.com/NTPsec/ntpsec/commit/c5ed321067a939c2d360fb78145a6bd314e16e22

The Cmd module should be importing readline for us, when available, since 2001. See:
https://github.com/python/cpython/commit/66b6e192b9d0437029f8fd7aa9f381bb4e9ed248

@Hal, can you double-check that the readline python module is importable on your system?  You might need libedit or GNU readline installed.

Would it help to add an informational check for this python module in waf's configure?
