Warning with loader Makefile?

I get this:
===> i386/cdboot
===> i386/kgzldr
===> i386/libi386
===> i386/loader
"/usr/share/mk/bsd.prog.mk", line 38: warning: duplicate script for target "loader" ignored
cc -nostdlib -static -Ttext 0x0 -o loader.sym
/home/obj/home/src/sys/boot/i386/loader/../btx/lib/crt0.o main.o conf.o
bcache.o boot.o commands.o console.o devopen.o interp.o interp_backslash.o
interp_parse.o ls.o misc.o module.o panic.o load_elf32.o load_elf64.o
isapnp.o pnp.o interp_forth.o vers.o

Why is there a duplicate script?
