Force Xcode SDK instead of CLI SDK?

The SDK in the and the SDK in the CLTs for MacOSX11.0.sdk are essentially identical (I just diff -ur'd them), so it doesn’t appear that the extra tools are in the SDK exactly. 

So from that point of view, the 10.15 SDK in the CLTs might still be used if there is a good reason to do so, as Josh points out, if Xcode could still find the other tools it is looking for.

The missing cdtool is here:

% locate cdtool                                                                 

I wonder how Xcode/xcodebuild goes about finding cdtools? It appears that xcodebuild is leveraging off the SDK location to find cdtools...
