We've got a new CI runner, which has probably a different CPU than the rest of the fleet, and here some LinearAlgebra doctests are failing because of a small differences of the results: https://buildkite.com/julialang/julia-master/builds/40579#01925a0d-05aa-4e4f-9490-52ead541ba20/799-865

These doctests should be more robust against variations due to the specific microarchitecture of the CPU where the CI job runs on, or these shouldn't be doctests in the first place if they are unreliable to be tested verbatim.
