Closed auto-roller. Looks like a real problem. Is anybody around to bisect this?

On linux_chromium_compile_dbg_ng the failures is:
FAILED: unittests exe.unstripped/unittests 
...
../../v8/src/isolate.h:223: error: undefined reference to
'v8::internal::ThreadId::GetCurrentThreadId()'

Range is https://chromium.googlesource.com/v8/v8/+log/bdd38862..51377461

I'll log off soon.
