If I move to a machine running MacOS 10.12.6, I can compile any version of TclTk I like. But I can compile none of them on my 10.15.7 machine. Is anyone else able to compile TclTk on MacOS 10.15?

What version of clang?

Can you share the output of:

    export CC="$(xcrun --find clang)"
    $CC --version

and also:

    xcodebuild -showsdks
