It's not in src/Makefile, it's in loadup.el, whicvh uses
add-name-to-file.

OK, thanks. So it shouldn't be a problem if the Windows build uses a
hard link in this case, I think, or a copy if the filesystem is FAT32
that doesn't support hard links. Creating symlinks is a PITA on
Windows, as they require privileges and pop up UAC prompts.
