    W32: Support cache paths relative to the root directory
    
    Paths starting with '/' don't make sense on W32 as-is,
    prepend the installation root directory to them.
    
    This allows the cache to be contained within a particular
    fontconfig installation (as long as the default
    --with-cache-dir= is overriden at configure time).
