The sandbox architecture is the only architecture so far that has been validated to build to completion with clang and function correctly afterwards. Until other architectures follow suit, fail the build gracefully for them. Note that in Linux, CLANG_TARGET_FLAGS_sandbox expands to $(CLANG_TARGET_FLAGS_$(SRCARCH)). This requires that we have support for non-sandbox architectures in the first place. Until we do, just make it a no-op by setting CLANG_TARGET_FLAGS to the same target triple that's used by default anyway.
