The best way is to go into the Makefile.am of each program compiled with
Objective C, remove any rules like

	SUFFIXES = .m
	.m.o:
		$(COMPILE) -c $<

and replace it with:

#-----------------------------------------------------------------------------
## Rules similar to `automake 1.2f' for building ObjC files, with dependencies
SUFFIXES = .m

OBJCFLAGS = $(CFLAGS)
OBJCCOMPILE = $(OBJC) $(DEFS) $(INCLUDES) $(CPPFLAGS) $(OBJCFLAGS)
LTOBJCCOMPILE = $(LIBTOOL) --mode=compile $(OBJCCOMPILE)

# ** This has to be called `LINK', not `OBJCLINK'
LINK = $(LIBTOOL) --mode=link $(OBJC) $(OBJCFLAGS) $(LDFLAGS) -o $@

gen_deps_o = @MAINT@-Wp,-MD,.deps/$(*F).P
gen_deps_lo = @MAINT@-Wp,-MD,.deps/$(*F).p

.m.o:
        $(OBJCCOMPILE) $(gen_deps_o) -c $<

.m.lo:
        $(LTOBJCCOMPILE) $(gen_deps_lo) -c $<
        @MAINT@@-sed -e 's/^\([^:]*\)\.o:/\1.lo \1.o:/' \
        @MAINT@ < .deps/$(*F).p > .deps/$(*F).P
        @MAINT@@-rm -f .deps/$(*F).p
