We built RDoc html with https://github.com/ruby/docs.ruby-lang.org/blob/master/Rakefile#L47

Is this working with `bundler/inline`? `Bundler.default_gemfile` will raise `Bundler::GemfileNotFound` under the `bundler/inline`. I confirmed that with this change and https://github.com/ruby/ruby/blob/master/spec/bundled_gems_spec.rb#L366. You can run that with `make bundled_gems_spec-run`.

Could you explain how work `lib/rubygems/rdoc.rb` and this change without plugin installation?
