Re: [PATCH v1 15/25] Deprecate 32 bit big-endian MIPS

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.
