Sample failing commands (printed from Python code):
CMD: ../../native_client/toolchain/mac_x86/pnacl_newlib/bin/x86_64-nacl-ar rcsD irt_x64/obj/native_client/src/untrusted/nacl/libimc_syscalls.a @irt_x64/obj/native_client/src/untrusted/nacl/libimc_syscalls.a.rsp
CMD: ../../native_client/toolchain/mac_x86/pnacl_newlib/bin/x86_64-nacl-ar rcsD irt_x64/obj/components/tracing/proto/libprotos.a @irt_x64/obj/components/tracing/proto/libprotos.a.rsp
CMD: ../../native_client/toolchain/mac_x86/pnacl_newlib/bin/x86_64-nacl-ar rcsD irt_x64/obj/third_party/ced/libced.a @irt_x64/obj/third_party/ced/libced.a.rsp

I've checked and `x86_64-nacl-ar` file is basically empty, so I had to remove the whole toolchain folder and re-run `gclient sync` again to fix it. I think it got empty, as I was experimenting with `afsctool` tool to compress natively Chrome sources on HFS+ and probably something went wrong. Similarly my git command binary got zeroed as well for some reason, so it could be some internal HFS+ macOS bug.

I think in the normal scenario this won't happen, so please close it.
