Alexander Egorenkov bbad15ae75 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.
