Re: [tsan] ThreadSanitizer instrumentation part

[Wei Mi <wmi@google.com>]

Hi Jack,

Koysta mentioned in a previous mail that tsan is only supported on
x86_64 linux (no 32-bits, no non-linux) for now. tsan building should
be disabled on the platforms other than x86-64-linux. Thanks to Jakub
who will provide another patch including this fix soon.

Thanks,
Wei.
