Which version of od are you using? I do recall wondering whether
reliance on the GNU coreutils extension --endian=big was going to cause
problems later - well, here we are, it's later :)
https://lists.gnu.org/archive/html/qemu-devel/2019-07/msg06781.html
coreutils documents that od --endian was added in 8.23, released in
2014-07-18. Per https://wiki.qemu.org/Supported_Build_Platforms, we
still have support for RHEL 7 through 2022, and it was first released
2014-06-09 (all other supported distros have newer releases, but I
didn't check what coreutils version they included, or even if the BSD
builds which don't use coreutils would also be impacted by this
problem). Still, I'd like to know your specific setup, and why the CI
tools have not flagged it.
But even one counterexample within the bounds of our supported distro
page is a good argument that use of od --endian is not yet portable.
Or, if your setup is not on the supported page, it becomes a question of
whether it should be added or whether you should upgrade to something
that is supported.
