67475dce - Driver: avoid linking against the C++ runtime

Driver: avoid linking against the C++ runtime Use `clang` rather than `clang++` as the linker driver. This ensures that we do not force a C++ runtime on the general code. This is fine for now as C++ interop is not yet available for Swift. This prevents the accidental mix-and-match of various C++ runtimes. This can cause problems on platforms like android where `libstdc++` is an unsupported runtime but is generally the default for Linux platforms.
