    docs: Fix install-man$(1)-pages if no manpages are generated
    
    All tools to build manpages are optional, and if none of them happen to be
    present, the intermediate working directory may not even be created.
    
    Treat this as non-fatal, bringing the behaviour in line with install-html.
    Like the html side, it needs to be not-or to avoid Make thinking the rule 
has
    failed.
