CI build failures

[Moritz Angermann]

You can safely ignore the x86_64-darwin failure. I can get you the juicy
details over a beverage some time. It boils down to some odd behavior using
rosetta2 on AArch64 Mac mini’s to build x86_64 GHCs. There is a fix
somewhere from Ben, so it’s just a question of time until it’s properly
fixed.

The other two I’m afraid I have no idea. I’ll see to restart them. (You
can’t ?)
