Why is this specific to __rtems__ while the type 'stack_t' is not ? 
Should this be feature rather than platform controlled ?

Is this only ever going to be used by RTEMS ? What if another user of 
newlib wants to use the API ? Should this be HAVE_SYS_CPUSET, 
PTHREAD_AFFINITY or something else ? I am not familiar with platform 
specific configs in newlib so I do not if this is possible.
