Please find rule in Makefile and apply following.

# Rule to build cygwin.dll
$(TEST_DLL_NAME): $(LDSCRIPT) dllfixdbg $(DLL_OFILES) $(DLL_IMPORTS) 
$(LIBSERVER) $(LIBC) $(LIBM) $(API_VER) Makefile winver_stamp
	$(CXX) $(CXXFLAGS) -Wl,--gc-sections $(nostdlib) -Wl,-T$(firstword $^) \
	-Wl,--heap=0 -Wl,--out-implib,cygdll.a -shared -o $@ \
  -e $(DLL_ENTRY) $(DEF_FILE) gcrt1.o $(DLL_OFILES) version.o winver.o \
  $(MALLOC_OBJ) $(LIBSERVER) $(LIBM) $(LIBC) boundbuffer.o instrument.o 
gmon.o mcount.o profil.o /lib/w32api/libkernel32.a \
  -lgcc $(DLL_IMPORTS) -Wl,-Map,cygwin.map
  @$(word 2,$^) $(OBJDUMP) $(OBJCOPY) $@ ${patsubst %0.dll,%1.dbg,$@}
  @ln -f $@ new-$(DLL_NAME)
