Xtensa port: Fixed scheduling bug caused to missing Endianess related macros.

Browse source 
XCC does neither define __BYTE_ORDER__ nor __ORDER_LITTLE/BIG_ENDIAN__ macros.
This resulted in field preempt of thread.base not correctly built from other
union fields prio and sched_locked, which caused wrong scheduling.
