No, you can do this at link time.  You have to know the right configuration 
parameters.  This should give the absolute minimum:

#include <rtems.h>

static void *idle_body(uintptr_t ignored)
{
   while (true) {
     /* Do nothing */
   }

   return NULL;
}

#define CONFIGURE_INIT

#define CONFIGURE_APPLICATION_DOES_NOT_NEED_CLOCK_DRIVER

#define CONFIGURE_APPLICATION_DISABLE_FILESYSTEM

#define CONFIGURE_DISABLE_NEWLIB_REENTRANCY

#define CONFIGURE_DISABLE_CLASSIC_API_NOTEPADS

#define CONFIGURE_UNIFIED_WORK_AREAS

#define CONFIGURE_MAXIMUM_PRIORITY 3

#define CONFIGURE_IDLE_TASK_INITIALIZES_APPLICATION

#define CONFIGURE_IDLE_TASK_BODY idle_body

#include <rtems/confdefs.h>
