[vlc-devel] [PATCH] Fix compilation from a git worktree

[Romain Vimont]

>From within a git worktree, "git describe" failed due to the explicit
--git-dir option:

      GEN      stamp-revision
    fatal: not a git repository: '../../.git/'

Let git find the actual git dir by just providing the path (-C) from
which we want to execute the git command.
