commit: http://git.buildroot.net/buildroot/commit/?id=5558a34e9ab8d53b4dafe3f760bff26d2df9c154
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Add a new option to graph-depends, that users can set to stop the graph
on a specific (set of) package(s).

This accepts any actual package name, or the 'virtual' keyword to stop
on virtual packages.
