Fire V445 support status

[Mark Linimon]

All that I can offer is that I have run 10.3 and 11.0 on V215s and V245s.
I had assumed that they were similar.

Although a few developers do work on sparc64, unfortunately there is
little support for it in general in the FreeBSD developer community.
I used to do package builds but have not during this year so far.

I am afraid we are in a shrinking minority.
