I currently don't have access to that machine and didn't worked on
config.guess before - so please create the patch yourself, if there
wasn't a change "upstream" yet.

The script queries the output of uname, which is on the machine I test

OS/390 S0W1 29.00 05 3931
because of OS/390 the script sets
*:OS/390:*:*)
GUESS=i370-ibm-openedition
The vendor ibm is correct, the os "openedition" _may_ be fine, but the
cpu type is definitely not correct, standing for the 32bit mainframe
architecture System/370 from 1970.
Instead, the cpu 3931 is part of the IBM Z architecture (z16, "Telum"
from 2022).
Maybe _if_ there is any cpu part just place it in there (or do a mapping
to zNN) or use a place holder like ibmZ?

Simon, could you submit a patch addressing this issue, please?
