Hi,

This is the same failure that was recently reported on the -stable@
list for stable/11 (entitled "building releng11 on RELENG12 broken
?"). It should only happen in the presence of WITHOUT_AUTO_OBJ, but
that shouldn't be the case on stable/12. It's clearly trying to
rebuild it into the src tree in the same way, though:

[/pool/sources/12-STABLE/src/bin/cp/utils.o] Error code 1

This is interesting, but I'm afraid I don't know the nanobsd build
well enough to understand what's going on here. I suspect it's
related, though.

Thanks,
