Feedback for ports on 12.1 stable snapshot/ppc64

[Kevin Smallman]

Can I also report that I've successfully also built llvm-80 and the whole
of xorg?
I feel like my imac deserves a reward for this, it's been at it for days.
The only problems so far have been when there are dependencies that need
python3, but the 'target' port is still thinks it's using 2.7.  So I had to
interrupt the process sometimes.
It's now busy on webkit.
