[Colin Walters <walters src gnome org>]

commit 9053ad07ba7210a5a2f8e7ca36f686fd9f96abe0
Author: Colin Walters <walters verbum org>
Date:   Tue Jun 21 10:26:58 2011 -0400

    Fix a srcdir!=builddir issue, and export that we support it
    
    Future jhbuild versions will consume the BUILD API and automatically
    use a builddir, so mark us as supporting it.
