commit 70a56b914772e6b21cda2a5742817ae4bb7290f1

    utils/mkdir-p: check if dir exists also after mkdir failed
    with "make install -j8" it happens very often that two or more make
    instances are creating the same directory in parallel. As a result one
    instace creates the directory and second mkdir fails because the
    directory exists already (but it did not while testing for it earlier).
