Thank you very much!  That's it:
# file /usr/bin/uname
/usr/bin/uname: ELF 32-bit LSB executable, ARM, EABI5 version 1 
(FreeBSD), dynamically linked, interpreter /libexec/ld-elf.so.1, 
FreeBSD-style, for FreeBSD 14.0 (1400051), stripped

Indeed.

Now the next thing (for me) to research is why the binaries were built 
"for FreeBSD 14.0 (1400051)" when the source tree has 1400063 and uname 
-U also reports 1400063.
FWIW, this was a cross-build, maybe that played a role too.
