How is it currently used on m68k and does QEMU use it? I think that would b=
e
certainly a way to go.

FWIW, I checked EI_OSABI on hppa out of curiosity:

glaubitz@panama:~$ uname -a
Linux panama 6.12.32-parisc64 #1 SMP Debian 6.12.32-1 (2025-06-07) parisc64=
 GNU/Linux
glaubitz@panama:~$ readelf -h /bin/bash|grep "OS/ABI"
  OS/ABI:                            UNIX - GNU
glaubitz@panama:~$

Compare that to x86_64:
