   sysconfig ought to be capable of handling this. If not, it should be made capable of handling it.

   We should not create links or copying extra source files around during build to satisfy these kinds of use cases - it's led to breakage in the past and will lead to it again in the future.

   If the metadata isn't available and the tools can't adapt, then the answer is for the user to use PC/layout to copy the build into a new place with a layout that the tools expect.
