Description
Initially, we had the rustdoc target build customized docs for the current kernel configuration. Then, in #446 (suggested in #442) we started using doc_cfg and the intention is that we build all the docs.
However, it could perhaps be useful to still allow users to build a customized version of the docs for the kernel configuration, e.g. for local development (i.e. faster generation) or for distributions that wish to provide t 5629 rimmed down docs for the kernels they release. See discussion at #446 for details.
For the moment, let's keep things simple. If somebody needs the feature, it is easy to implement (although it may require some churn to move to a doc_all gate instead of the doc one).
