[Thomas Petazzoni]

commit: http://git.buildroot.net/buildroot/commit/?id=f8c0e45d3236c8005b30d12a7f49c225603dad96
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

distclean is supposed to return the current directory, whether in-tree
or out-of-tree, into pristine conditions, which means we should also
forget about any br2-external tree on distclean.
