commit 751fc7802f57a836a0be5fc6a8d5fdf8b1769c39
Author: Richard Purdie <richard.purdie at linuxfoundation.org>

    oeqa/selftest: Add package hardlink test
    
    We keep breaking the preservation of hardlinks during the packaging process.
    Add a selftest which tests this to try and prevent this breaking again.
