My latest bisecting has shown this change to be the responsible change, CC'ing the author:
commit 73fc4e28b9464f0e13edc719a5372839970e7ddb (refs/bisect/bad)
Author: Florian Weimer <fweimer@redhat.com>
Date: Mon Feb 28 11:50:41 2022 +0100
Linux: Consolidate auxiliary vector parsing (redo)
And optimize it slightly.
This is commit 8c8510ab2790039e58995ef3a22309582413d3ff revised.
In _dl_aux_init in elf/dl-support.c, use an explicit loop
and -fno-tree-loop-distribute-patterns to avoid memset.
