    Makefile: Streamline directory creation · c964d962
    Michael Hanselmann authored
    Some directories don't exist in the repository, but are required at build time
    (e.g. doc/html). Until now some were created explicitly, some through the
    target “stamp-directories” and other target simply relied on a previous target
    to create the directory.
    
    This patch tries to clean this up by getting rid of “stamp-directories” and
    instead use rules to recreate any missing directory. As described in a comment
    in the code, a file inside each directory is necessary, named “.dir”.
    
    Order-only dependencies are used for directory creation to avoid rebuilding
    where only the “.dir” file is missing (see “info make”, section “4.3 Types of
    Prerequisites”).
    
    The target for building the documentation is also changed to use “…/index.html”
    instead of a hidden file. Some style changes are also made.
