I mostly agree. Question is whether we really need all of them, e.g. do we 
really need both, the *-armel and the *-armhf jobs for both, the -user and 
the -system part? Or would it be still ok to e.g. only have a -armel-user 
and a -armhf-system job and drop the other two?

I think there are also other possibilities where we could cut down CI 
minutes, e.g.:

- Avoid that some of the -softmmu targets get build multiple
   times

- Re-arrange the Avocodo jobs: We should maybe rather sort them
   by target system instead of host distro to avoid that some
   targets get tested twice here.

- Do we really need Linux-based clang jobs if we test Clang
   compilation with macOS and FreeBSD, too?

- Would it be OK to merge the merge the build-without-default-
   devices and build-without-default-features jobs?

And after all, I'd like to raise one question again: Could we finally stop 
supporting 32-bit hosts? ... that would really help to get rid of both, some 
CI minutes and some maintainer burden.
