Doc make change

[Adam Fedor]

I'd like to commit this patch. Here the make won't abort if the user 
doesn't have the corect doc building programs. That way we can enable 
automatic building of documentation (e.g. in base, gui, etc) without 
worrying that the build will fail if a user doesn't have the right 
programs. Ok?
