I tried a tinderbox build right now and saw the lld warnings from
linking zfs.ko. It appears to be fallout from the change to build
clang and lld only once for tinderbox, because we're invoking ld from
the ${HOST_TARGET} path:
/scratch/tmp/emaste/obj/scratch/tmp/emaste/freebsd/freebsd11-amd64/tmp/usr/bin/ld
-m armelf_fbsd -Bshareable -znotext -d -warn-common --build-id=sha1
-o zfs.ko.full zfs.kld
/scratch/tmp/emaste/obj/scratch/tmp/emaste/freebsd/freebsd11-amd64/tmp/usr/bin/ld:
warning: lld uses extended branch encoding, no object with
architecture supporting feature detected.
/scratch/tmp/emaste/obj/scratch/tmp/emaste/freebsd/freebsd11-amd64/tmp/usr/bin/ld:
warning: lld may use movt/movw, no object with architecture supporting
feature detected.
