const char *rtems_version_control_key( void )
   return NULL;

returns NULL, if no RTEMS_VERSION_VC_KEY is defined, e.g. the RTEMS 
sources are not managed by Git. Naive users like me may produce a NULL 
pointer if they use it like this printf("version: %s", 
rtems_version_control_key()). Should we change this function to return 
"" instead of NULL?
