Android may end up wanting to use it for the same reason. I've backed it out for now, but it may end up being something we need since a fair number of NDK users (majority, probably) use libsupc++ and that might be a point of pain in migrating to libc++abi. Other Linux distros may want it as well, so probably worth leaving the code around.
