Aha, that makes sense. I'll try to find where v3 leaks out. So far it looks
like some rtld files need newer ISA:

$ LANG=3DC h readelf -a $(find -name 'rtld-*.o*') |& egrep 'File|v3' | fgre=
p -B1
v3
File: ./string/rtld-strcspn-c.os
      Properties: x86 ISA used: x86-64-baseline, x86-64-v3
--
File: ./gmon/rtld-profil.os
      Properties: x86 ISA used: x86-64-baseline, x86-64-v3
--
File: ./signal/rtld-sigaction.os
      Properties: x86 ISA used: x86-64-baseline, x86-64-v3
