Since there is always an rseq area of at least RSEQ_AREA_SIZE_INITIAL
(32 bytes) allocated even when rseq is disabled, we should always add
the range to the test, something like that :

 +static void
 +add_rseq (void)
 +{
 +  add_range ("", "rseq area", (char *) __thread_pointer () + __rseq_offset,
 +  	MAX (__rseq_size, RSEQ_AREA_SIZE_INITIAL));
 +}

Thanks,
