service_discovery_sniffer built broken on Clang bot

Project Member Reported by thestig@chromium.org, Dec 19 2017 
There is a service_discovery_sniffer build target that's breaking here:

https://ci.chromium.org/buildbot/chromium.clang/ToTLinuxASan/957

r524534 is likely what broke it, though I can't repro this breakage locally with my generic non-component Linux build.

Comment 1 by thestig@chromium.org, Dec 19 2017 

The bot's build config is:

clang_use_chrome_plugins = false
is_asan = true
is_clang = true
is_component_build = false
is_debug = false
is_lsan = true
llvm_force_head_revision = true

I tried setting everything except "llvm_force_head_revision = true", and I added "use_goma = true", and it links for me.

When I tried to set "llvm_force_head_revision = true", it assumed I have LLVM checked out into third_party/llvm, which I don't. So "gn gen" fails. Haven't looked into what I need to do to run ToT Clang.

@thestig you need to build clang from source
$ tools/clang/scripts/update.py --force-local-build

Comment 4 by thomasanderson@google.com, Dec 19 2017 

Oh, and the Clang ToT bots also use --llvm-force-head-revision

Comment 5 by thestig@chromium.org, Dec 19 2017 

Ya, I was hoping to not have to build Clang, but I know the script automates it, so here goes...

Status: WontFix (was: Untriaged)
And finally after hours of building... it succeeded. So did the bot.

And I bet r524954 fixed it. Wee!
