obfsproxy: use -fno-strict-aliasing
Obfsproxy is doing the C-OO structures trick, and is using sockaddr/ sockaddr_in/ sockaddr_storage in normal ways. This will make GCC's strict alias checking generate incorrect code under annoying circumstances. When building with GCC, obfsproxy should make sure that the -fno-strict-aliasing flag is passed to the compiler, or expect a big fun surprise.
