Build failure during main-n290063-3ceb5f150bc1 => main-n290084-b5e6d60e57ba

First system was running

FreeBSD freebeast.catwhisker.org 16.0-CURRENT FreeBSD 16.0-CURRENT #55 main-n290063-3ceb5f150bc1: Mon Oct 12 10:55:18 UTC 2026     root@freebeast.catwhisker.org:/common/S4/obj/usr/src/amd64.amd64/sys/GENERIC amd64

I had updated sources to main-n290084-b5e6d60e57ba; failure showed up
rather early.  Here is what is in the first part of the ERROR_META_FILE:
