There is this snip in src/share/mk/bsd.own.mk that indicates that ZFS is
only on 64 bit systems.

#
# We want to build zfs only for amd64, aarch64 and sparc64 by default for now.
#
.if ${MACHINE} == "amd64" || \
    ${MACHINE} == "sparc64" || \
    ${MACHINE_ARCH:Maarch64*}
MKZFS?=         yes
.endif


At one time, the ZFS libraries (at the very least) were built on 32 bit
systems, but that stopped happening some time ago.  This PR may have
just stumbled upon a dead branch.  I know that when I tried to build ZFS
on i386 a short time ago in -current it blew up and wouldn't compile a
release.
