We have such automatic dependencies in a large number of packages, we
simply can't add sub-options for each and every features. Since this
one is not necessarily trivial, I've added in the commit an additional
paragraph in the Config.in help text to hint the user about the need to
enable elfutils to get debug info support.

Best regards,
