v2: send on behalf of Bruce on request.
    - tell sphinx to create .doctrees working files in the
      parent of the target directory so that they don't get
      installed
    - change the output directory so that it matches the legacy
      makefiles directory structure (on install)
    - add install_dir to fix ninja install
    - add post-install calls to delete .buildinfo sphinx
      temporary file and to install custom.css as the makefiles
      do
The installed directory has been verified to be bit-by-bit
identical to the legacy makefiles with diffoscope.

v3: re-arranged sphinx parameters to make it work on older
    versions  (RHEL 7), and specify DEST filename on the
    install call, to make it work on older version (RHEL 7)
