The goal of the snapshot bots is to produce binaries which can run in as many locations as possible. Currently we build on Centos 6 for this reason, but with LLVM's update to C++11, this reduces the number of platforms that we could possibly run on. This adds a --enable-llvm-static-stdcpp option to the ./configure script for Rust which will enable building a librustc with a static dependence on libstdc++. This normally isn't necessary, but this option can be used on the snapshot builders in order to continue to make binaries which should be able to run in as many locations as possible.
