FTBFS on 32bit is expected, as far as I am aware and won't be fixed.
Build on s390x is fixed in the latest mantic uploads. So marking this as
fixed.

Title:
FTBFS on s390x and armhf
Status in blender package in Ubuntu:
Fix Released
Bug description:
a) s390x FTBFS:

I checked upstream git repo and that code is still the same in the
main branch. I also didn't find any open or closed issues dealing with
this type of build error. This warrants more investigation, maybe an
upstream issue.
