According to a recent [discussion on IRC](https://botbot.me/mozilla/rust-tools/2015-10-27/?msg=52887517&page=2), there's no good reason for Windows builds to store target libraries under `bin`, when on every other platform they are under `lib`. This might be a [breaking-change] for some users. I am pretty sure VisualRust has that path hard-coded somewhere. r? @brson
