genlink: provide LIBDEPS for libopencm3 itself
If $(OPENCM3_DIR)/lib/libopencm3_*.a exists, it will be linked in.
If we do that, we should also add it to the deps.
That way a newer *.a will result in a relink.
To use this, you should add a dependency to $(LIBDEPS) where you are
using $(LDFLAGS) and $(LDLIBS) now.
eg, old (wouldn't relink if the library changed)
$(PROJECT).elf: $(OBJS) $(LDSCRIPT)
@printf " LD\t$@\n"
$(Q)$(LD) $(TGT_LDFLAGS) $(LDFLAGS) $(OBJS) $(LDLIBS) -o $@
new (will relink when the library changes)
$(PROJECT).elf: $(OBJS) $(LDSCRIPT) $(LIBDEPS)
@printf " LD\t$@\n"
$(Q)$(LD) $(TGT_LDFLAGS) $(LDFLAGS) $(OBJS) $(LDLIBS) -o $@
