At first look, I'm not a big fan of this solution, as it requires a lot
of knowledge from the Buildroot user about dependency details that
precisely Buildroot is supposed to handle.

I'd prefer to understand why and when these gconv files are needed, and
depending on that, see how it should fit in our configuration system.
