To deal with the above issue, I've started a from-scratch build sequence
of the same subset of port-packages on the 7950X3D. That should make for
time ratios that are more reasonable to compare/contrast.

I happened to have set the sequence to 15.0 then 14.4 then 14.3 .

[I've also corrected my prior inclusion of freebsd-current@ to be
freebsd-arm@  instead.]
