    build: add more top-level files to EXTRA_DIST
    
    To distribute them in tarballs.
    - autogen.sh: could be useful, but it's normally ./configure that needs
      to be executed. In any case, it doesn't hurt to include autogen.sh (I
      think it could be useful for MSYS2 packaging, so for Windows).
    - README.md: this is of course important.
    
    What's still missing, and I don't really know:
    - git.mk: not distributed in tarballs, but of course this is for Git
      purposes, not for tarballs. So I guess it's fine.
