I checked _TLS_Get_allocation_size(). It already returns the maximum 
size if it is configured:

     if ( _Thread_Maximum_TLS_size != 0 ) {
       if ( allocation_size <= _Thread_Maximum_TLS_size ) {
         _Assert( _Thread_Maximum_TLS_size % CPU_STACK_ALIGNMENT == 0 );
         allocation_size = _Thread_Maximum_TLS_size;
       } else {
         _Internal_error( INTERNAL_ERROR_TOO_LARGE_TLS_SIZE );
       }
     }
