It'll point to the original source tree if you're running Emacs out of 
the build directory. If you're running Emacs out of the installed 
directory, it will point to the installed source tree.

Although we can do that, generally speaking it's better when there's no 
difference between reproducible and irreproducible builds, as that's one 
less thing to worry about when maintaining and debugging.
