    Delay expansion of documentation install wildcard
    
    * build/doc-reference.am (htmlref_files): Revert to a recursively
    expanded variable instead of assigning the list of files statically.
    The recent build overhaul changed the order of variable expansion,
    and $(htmlref_files) ended up empty.
