This should not be a concern if you are organizing your content in a clear taxonomical structure that resembles a pyramid, with the home page being the most general expression of what the site is about, and the next levels becoming more specific, with the pages at the bottom being the most granular (long tail) expressions of the topic.
Now you target the link building not just to the home pages but to the second and third clicks down.
