    Fix mkdirhier.sh on OS X 10.9 (#8139)
    
    Mac OS X 10.9 mkdir is apparently stricter than the Mac OS X 10.8
    mkdir about which paths are considered valid arguments. For example,
    in a typical build on Mac OS X 10.9, the first of the following
    invocations of mkdirhier.sh will succeed but the second will fail:
    
    "inplace/bin/mkdirhier"   utils/ghc-cabal/dist/build/tmp//.  # WORKS
    "inplace/bin/mkdirhier"   bootstrapping/.                    # FAILS
    
    Simply prefixing the path arguments with "./" causes both to succeed:
    
    "inplace/bin/mkdirhier" ./utils/ghc-cabal/dist/build/tmp//.  # WORKS
    "inplace/bin/mkdirhier" ./bootstrapping/.                    # WORKS
    
    Testing indicates failure on paths satisfying all of these criteria:
    
    - path is suffixed with "/."
    - path is only 1 level deep (e.g., "foo/."; _not_ "foo/bar/.")
    - path is _not_ prefixed with "./"
    
    This workaround prefixes "./" to the path argument passed to mkdir.
