Kbuild provides LDFLAGS_MODULE to allows users to give additional options for linking modules, but there is no way to append flags for linking vmlinux. It is true LDFLAGS_vmlinux specifies the linker options for vmlinux, but it is only for internal-use. We have CFLAGS_KERNEL, AFLAGS_KERNEL already, so LDFLAGS_KERNEL is the same pattern.
