Clang for macOS requires -lto_library

Hi,
I downloaded
Clang for macOS

However if I use -fuse-ld=lld it complains
“Unable to find library for -lto_library”

CLANG = clang

CLANG_PATH = ~/Downloads/clang+llvm-6.0.0-x86_64-apple-darwin/bin
CFLAGS =
RM = rm -f
TARGET = x86_64-apple-darwin17.4.0
EXE = Test.exe

default: clean all

all: $(EXE)

$(EXE): test.c
$(CLANG_PATH)/$(CLANG) -v
-fuse-ld=lld
-target $(TARGET)
-o $@ $< $(CFLAGS)

clean:
$(RM) $(EXE)

Thanks
