Look up uname().  It fills in a struct utsname * and reports the
information you want.  cpukit/libcsupport/src/uname.c ...

  strcpy( name->sysname, "RTEMS" );
  sprintf( name->nodename, "Node %d", _Objects_Local_node );
  strcpy( name->release, RTEMS_VERSION );
  strcpy( name->version, "" );
  sprintf( name->machine, "%s/%s", CPU_NAME, CPU_MODEL_NAME );
