I strongly believe that this is a duplicate of LP#2055175, which is
meanwhile Fix Released and should be included in the latest noble/24.04
daily images.

glibc in noble (release) is currently (Apr 10th) 2.39-0ubuntu8
and
glibc 2.39-0ubuntu7 changelog incl:
    - S390: Do not clobber r7 in clone [BZ #31402] (LP: #2055175)

So I consider this as duplicate and closed/Fix Released.

Please feel free to object, in case you think this is not fixed or if
there is another issue.
