Yes, I think this is a regression in some other component, probably Mesa
or LLVM. 1.26.4+dfsg-2 passed unit tests on the buildds, but when rebuilt
on eller with current versions, it fails the same 5 tests as 1.26.4+dfsg-3
(although the failure is ignored by the d/rules from 1.26.4+dfsg-2).

This might be related to https://bugs.debian.org/935884 and/or
https://bugs.debian.org/868745, which are other mips-specific crashes
involving llvmpipe.

I'm now trying to build 1.26.4+dfsg-2 on eller to see whether this is a
regression in some other package - I suspect it was, since clutter-1.0
has had no code changes since 2020, but it would be good to be more sure
of this.
