The build script does make some assumptions here, one of them being that it has control over the installed SDK's. PR's are welcome to make it more resilient when running on a dev machine where things like an SDK is already installed.

In retrospect, I believe that there is a way that one can pass a untarred SDK path directly to swift build and maybe that's the way that this script should work so that it doesn't impact the user's environment.

FYI, you can pass --swift-sdks-path to the swift build invocation to tell it where your Swift SDKs are at. So if you download the static SDK locally in some temp folder, you can do:

swift build --swift-sdks-path /path/to/tmp/directory --swift-sdk <arch>-swift-linux-musl
