So what do we do know about this problem?
We could just assume that the directory given with grub-setup
--directory is already the real absolute path and just use the stat
magic to make it relative.
Or we use realpath() if avaible to get the real one.
And on systems not having it, like mingw we could just assume that it's
already relative and just return the path given.
Or is there some other way this bug can be fixed?
