The lower-common-denominator approach is a bit frustrating. How does
FreeBSD compile U-Boot? What are you actually using that system for if
it cannot build U-Boot?

Re 1) I found an open in ld to produce the standard link script. I
actually used that before I found INSERT BEFORE.

Before giving up I think it would be worth exploring 1). It should
then be possible to make sandbox work also.

Finally, please point me to how I can install FreeBSD in viritualbox
or similar. I'm interested in that...
