target: support of big-endian architectures
* Introduce the new target flag 'LittleEndian' which specifies
of which endianness the target is.
* Introduce the new requires flag 'littleendian' for tests to
selectively enable/disable tests on either little-endian architectures
or big-endian ones.
* Disable KD unit test on s390x architecture because the test
works only on little-endian architecture.
