Some build systems appear to be using an old macOS SDK even though the macOS 11 SDK is available. We should run `xcode-select` to point these machines to the macOS 11 SDK. It may also be prudent to remove the old SDKs from these systems at the same time. At a minimum, this appears to affect `OS X opt/debug` builds and causes build bustage due to the landing of bug 1696513.
