It's becoming harder to maintain a cross-compiler to test this host architecture as the old stable Debian 10 ("Buster") moved into LTS which supports fewer architectures. For now:
- mark it's deprecation in the docs - downgrade the containers to build TCG tests only - drop the cross builds from our CI
Users with an appropriate toolchain and user-space can still take their chances building it.

For completeness we should update meson.build to consider host_machine.endian() and adapt this section:

This can be done later, and I might be able to do so in few weeks, so meanwhile (with Thomas comment addressed): Reviewed-by: Philippe Mathieu-Daudé <f4bug@amsat.org>
