@jfgrimm sorry for the failures, seemingly the versions are not really incremental so some patches I thought would still apply didn't. As can be seen by recent test reports this is now fixed.

@boegelbot please test @ generoso

I'm still seeing test failures on my machine:

although I think that's unrelated to the changes in this PR, so shouldn't block this

Going in, thanks @Flamefire!

Seems like I introduced a bug here for 2.2 and 3.0: They don't support POWER10 so the code doesn't compile on any PPC. Fix included in #15889

This still doesn't fully solve the BLIS build on PPC due to segfaults in 0.9.0 (flame/blis#621) and timeouts during tests in 3.0.1
