For the system > compiler, I believe this behavior is a strict improvement. No, apple's clang doesn't have a default sysroot. When you run `/usr/bin/clang`, which is a shim that calls `xcrun`, it finds the clang in your toolchain and invokes it with `SDKROOT` environment variable. That is the behavior of the shim, not the behavior of clang.
