I don't have a log, unfortunately, because I'm always building on eller or
minkus where I cannot use sbuild but just run dpkg-buildpackage directly. I
can, however, run the output through "tee" to get a logfile.

The error looked very similar to the one we have seen on 32-Bit ARM targets,
see [1]. The same workaround used for arm* in the debian/rules file didn't
help on mips* though.

No idea. I just know there is apparently still a bug in the atomics code
on mips* in LLVM, see [2].
