FreeBSD runs Many officially ported packages

To avoid different berklix pages inconsistently quoting different { numbers of ports, FreeBSD releases & dates } those web pages point here for consistency.
Pedant's Note: The other pages generally have text that links on
as tens of thousands of packages"
I freely acknowledge 17,000+ is not technically >= 20,001, but it will be soon enough, & will save save editing later.
