No, that doesn't seem worth it.

That seems fine, if it will work. The key criteria are:
(1) You can do it in such a way that it's obvious it doesn't affect
other platforms.
(2) You can do it quickly.
Engineering beauty is not a consideration at all, in this case.
#ifdef __s390__ is fine, for example; if you can just do
#ifdef __s390__
cfa += 196;
#endif
that is absolutely fine by me.
If we can't meet those criteria, we may be forced to punt; s390 is not a
primary evaluation platform.
Please see if you can get this fixed in the next twenty-four hours or
so.
Thanks,
