 In reviewing RTEMS+newlib POSIX conformance, I noticed that our newlib
 configuration does include the exec*() variants. All of these call
 _execve() which we already provided.

 This ticket is just to explain the removal of the RTEMS copies. The
 functional behavior to the user is still to return ENOSYS.
