CORRECTION to ADDED: Back on 2018-Nov-11 I reported successful cross-builds
based on qemu-user-static from ports head -484783 --all built under FreeBSD
head -r340287 . So the use of the perl5.28 as the forced-default and the
newer FreeBSD head version -r341836 as the context are the differences here.
