Not free, but an excellent book along the same lines, is John Levine's "Linkers and Loaders":

He's been the moderator of comp.compilers since 1986, so he's got a lot of practical Q&A experience to draw on.

I can't comment on its "goodness" but the textbook that sprang to mind is Linkers and Loaders: http://www.amazon.com/Linkers-Kaufmann-Software-Engineering-...

The bad news is that it's from '99 but, as far as the foundations go, I can't imagine linkers back then were that different.
