I don't have a reproduction. While this does look like a problem with
the build (because that path is fairly unique and comes from my build
machine), I don't see this at my end. I've no idea why it would have got
there. I have checked both the installer and zip.

I did try grepping through an unpacked Emacs and paths from the build
machine *do* appear in several places. For example:

But not the lisp directory.

@Wayne have you used the snapshot that is currently on alpha? Or is it
an older one?
