Adhemerval from glibc upstream is aware of the problem but he has not found yet a solution
to this issue as it needs to be debugged further. I will try to bisect which particular
introduced the regression and file a new upstream bug report.
During our discussion, Adhemerval pointed out that this change [3] might be the culprit
but I have not been able to verify this yet.
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>

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.
