We keep the older 11.0 and 10.11 SDKs for openh264. Ideally, we'd rename the SDK directory not to contain its version, but ld64 actually relies on the directory name to figure out the platform version when it's not given to it, which it's not. We can make clang do that, but it's rather involved (because it also requires setting up the host linker properly, which we don't do), so we just go the easy route and keep the SDK version in its directory.
