For many individual modules may need check CPU_LITTLE_ENDIAN or
CPU_BIG_ENDIAN, which is an architecture's attribute.

Or they have to list many architectures which they support, which they
don't support. And still, it is not precise.

For architecture API, endian is a main architecture's attribute which
may be used by outside, so every architecture need let outside know
about it, explicitly.

Thanks.
