Hum, are you sure your question was whether we should download it or
keep it inside Buildroot? I think your question was more "is it
possible to keep it inside Buildroot?", to which I answered yes,
indeed :-)

But anyway, doesn't really matter. I personally believe it's better to
download stuff when we can rather than bundling it. Hopefully others
will agree with me.

A Config.in that is not included anywhere is not useful at all, so it
shouldn't exist.

Alright, so it can be used in <pkg>_SOURCE. You will have to overwrite
the EXTRACT_CMDS however, because it's not a tarball. See jquery.mk for
example.
