A ./build.sh -x tools distribution sets on one core of an amd64 system 
took 8711.28 real. If that was 344 times faster than a 4000/60, then the 
4000/60 should take around 34.7 days. My build has been running since 
25-December, but an accidental break on the serial caused it to lose three 
or four days, so that's around 33 days.

The log on the VAX is about 60% of the size (55% of the line count) of the 
finished log on the amd64 system, giving a rough suggestion of about 58
days (based on the 60% number), or another 25 days or so.

Does that mean my amd64 system (Ryzen 5900X) is 1.7 times faster than 
yours? ;)

I know our math is completely based on the wrong kind of measurements, but 
it's fun to wonder.
