bcheck.o is part of libtcc1.a. See lib/Makefile:

BCHECK_O = bcheck.o
(…)
I386_O = libtcc1.o alloca86.o alloca86-bt.o $(BCHECK_O)
X86_64_O = libtcc1.o alloca86_64.o alloca86_64-bt.o $(BCHECK_O)
(…)
ifeq "$(TARGET)" "i386"
 OBJ = $(addprefix $(DIR)/,$(I386_O))
(…)
ifeq "$(TARGET)" "x86_64"
 OBJ = $(addprefix $(DIR)/,$(X86_64_O))
(…)
$(DIR)/libtcc1.a ../libtcc1.a : $(OBJ) $(XAR)
        $(XAR) rcs $@ $(OBJ)
