Could you give a bit of background on the different webkit "variants" ?
Why do they apparently duplicate the same webkit code ?

Actually, what François did is standard Buildroot practice. We very
often prefer to use "automatic dependencies" (i.e automatically enable
feature FOO if its necessary dependencies are available) rather than
"explicit dependencies (i.e add an explicit Config.in option to enable
feature FOO, which would select the necessary dependencies).
The reasoning for that is simple: we are trying to avoid having
gazillions of Config.in options.
However, we don't have any strict rule on this, and in some situations,
it makes sense to have an explicit option, especially when the
relationship between the needed dependencies and the feature is not
