Rust adds some new clang dependencies; specifically:
ninja: error: '../../third_party/llvm-build/Release+Asserts/lib/clang/17/lib/x86_64-unknown-linux-gnu/libclang_rt.builtins.a', needed by 'obj/third_party/protobuf/libprotoc_lib.a', missing and no known rule to make it
This is in the libclang-rt-14-dev package, but with a different (and
architecture-specific) path. So we special-case linux instead of
doing the same thing that upstream does w/ chromeos.
