Should the man-page tcp_rack(4) be changed at the same time to mention TCP_BLACKBOX as an optional dependency (and what feature it unlocks in rack)?

I think the way to go would be to add a man page for TCP Black Box Logging (BBLog). It allows logging events and packets for the FreeBSD base stack, the RACK and the BBR stack. Logging is most detailed for the RACK stack. Please note that TCP_BLACKBOX is enabled by default.

Adding a BBLog man-page has no relation to fixing the build problem.
