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.

+A Debian 10 ("Buster") moved into LTS the big endian 32 bit version of
+MIPS moved out of support making it hard to maintain our
+cross-compilation CI tests of the architecture. As we no longer have
+CI coverage support may bitrot away before the deprecation process
+completes. The little endian variants of MIPS (both 32 and 64 bit) are
+still a supported host architecture.
For completeness we should update meson.build to consider
host_machine.endian() and adapt this section:
if not supported_cpus.contains(cpu)
message()
warning('SUPPORT FOR THIS HOST CPU WILL GO AWAY IN FUTURE RELEASES!')
message()
message('CPU host architecture ' + cpu + ' support is not currently
maintained.')
...
This can be done later, and I might be able to do so in few weeks,
so meanwhile (with Thomas comment addressed):
