The binary was build by myself.
Find below a condensed makefile which I used for tests. I think that the 
dependency section is not necessary, it contains some special stuff for 
adapting .o to .obj by means of sed.

CC         = gcc
AS_CPP            = gcc
AS                = as
AR              = ar
SED               = ./sed
RM                = rm -f
MD         = ./mkdir -p
TEST         = test

local_lib = $(OBJ_DIR)local.lib

all: $(local_lib)

local_src = $(wildcard SOURCE/*.c)
#local_src = SOURCE/file1.c SOURCE/file2.c

c_depends := $(subst .c,.d,$(local_src))
c_depends := $(addprefix $(OBJ_DIR), $(c_depends))
c_objects := $(subst .c,.obj,$(local_src))
c_objects := $(addprefix $(OBJ_DIR), $(c_objects))

#$(warning @@@ c_depends=$(c_depends))
#$(warning @@@ c_objects=$(c_objects))
