Ok, I did some more tests today. First two runs were simply killed:

 https://cirrus-ci.com/build/5478092878381056
 https://cirrus-ci.com/build/5754149284085760

Then I tried to decrease the amount of resources to 4 CPUs and 8G of
RAM, but that timed out:

 https://cirrus-ci.com/build/6003268728651776

Then I finally increased the CPUs back to 8 again, but stick with 8G of
RAM, and that indeed finished in time successfully:

 https://cirrus-ci.com/build/6218565876187136

So yes, looks like 8 CPUs should work indeed, but I think you should
decrease the amount of memory of the VM, to make sure that it does not
get killed so easily. 8 GB of RAM should also be enough to compile QEMU,
as far as I can tell.

PS: I also removed the V=3D1 in my tests since otherwise the log was way
to verbose for my taste ... but that's likely really just a matter of tas=
te.
