    ensure that IMAGEDIR exists (thus globbable) · e46c259a
    Michael Shigorin authored
    It appears that manually specified IMAGEDIR, e.g. by adding
    
      IMAGEDIR = ~/out/$(shell date +%Y%m%d)
    
    to ~/.mkimage/profiles.mk, might be problematic due to
    missing globbing.  Let's make sure the paths are globbed
    and directories are created -- since make's wildcard()
    returns an empty string when there's nothing there [yet].
