    Fix PR 19089: Environment variable TMP may yield gcc: abort

    Even though I cannot reproduce the ICE any more, this is still
    a bug. We check already to see if we can access the directory
    but never check to see if the path is actually a directory.

    This adds the check and now we reject the file as not usable
    as a tmp directory.

    OK? Bootstrapped and tested on x86_64-linux-gnu with no regressions.

    libiberty/ChangeLog:

            * make-temp-file.c (try_dir): Check to see if the dir
            is actually a directory.
