    openssl/fontconfig/bzip2: Use relative symlinks instead of absolute ones (using a new class)
    
    Absolute path symlinks are a bit of a pain for sstate and the native versions
    of these recipes currently contain broken symlinks as a result. There are
    only a small number of problematic recipes, at least in OE-Core, namely the
    three here.
    
    Rather than trying to make sstate handle this magically, which turns out to
    be a harder problem than you'd first realise, simply make the symlinks relative
    early in the process and avoid all the problems.
    
    The alternative is adding new complexity to sstate which we could really
    do without as without the complexity, you can't always tell where the
    absolute symlink is relative to (due to prefixes used for native sstate).
    
    (From OE-Core rev: e478550c8cd889f12e336e268e9e3b30827bf840)
