I've slightly improved this script, and it is now capable of generating
the dependency graph for a full Buildroot configuration, i.e taking
into account all packages that have been selected.

See http://free-electrons.com/~thomas/buildroot-full-dependencies.pdf
for a fairly large example involving X.org and Gtk.

As always, the code is available in
http://git.buildroot.net/~tpetazzoni/git/buildroot/log/?h=graph-dependencies.
Besides the modifications in the script itself, the modifications in
the rest of Buildroot are very small.
