You shouldn't..  It's elf-only by design - it's an emulation for linker 
sets that the a.out ld did.

bsd.kmod.mk should be handling all this for you already:

.if defined(KLDMOD)
.if ${OBJFORMAT} == elf
        gensetdefs ${OBJS}
        ${CC} ${CFLAGS} -c setdef0.c
        ${CC} ${CFLAGS} -c setdef1.c
        ${LD} -Bshareable ${LDFLAGS} -o ${.TARGET} setdef0.o ${OBJS} setdef1.o  
${KMODDEPS}
.else
        ${LD} -Bshareable ${LDFLAGS} -o ${.TARGET} ${OBJS} ${KMODDEPS}
.endif
.else
        ${LD} -r ${LDFLAGS:N-static} -o tmp.o ${OBJS}
[..]

Cheers,
-Peter
