RCR 155: Include CONFIG::Config['rubydocdir'] in rbconfig.rb

This is a legacy RCR from Ruby Garden, submitted by Gavin. Matz has declared these RCRs obsolete, and asked that their authors resubmit them in the new format.

Ruby would benefit from the introduction of a standard documentation directory. This one seems sensible for Unix-like platforms:

  /usr/[local/]doc/ruby/

A similar path in a Windows install would look like this:

  C:/ruby/doc/ruby

The benefit of agreeing on a standard and implementing it is that package installers could use it to install package documentation in a known place.

In order to implement this, we need to change mkconfig.rb so that in a Ruby installation, the documentation directory is accessible via rbconfig.rb, just as we find the "site_ruby" directory and others in this way.

Therefore, I propose that the following line be included in rbconfig.rb (the first line is an existing one for reference):

  CONFIG["rubylibdir"] = "$(libdir)/ruby/$(ruby_version)"

+ CONFIG["rubydocdir"] = "$(prefix)/doc/ruby"

Roll on decent, installed package documentation!
