+As Debian 10 ("Buster") moved into LTS the big endian 32 bit version of
+MIPS moved out of support making it hard to maintain our

+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.
