Issue Description:

The following Sanitizers test failures are seen when Swift 5.0 toolchain is built on PowerPC64LE.

Invoked the build-toolchain to run the tests as follows :-
utils/build-toolchain srtbundle --test

**Following are the Sanitizers test failures:-

Swift(linux-powerpc64le) :: Sanitizers/tsan.swift
Swift(linux-powerpc64le) :: Sanitizers/witness_table_lookup.swift

Are these tests valid for PowerPC64LE?

Attached are the error details of the failing tests.

Does TSan work on PowerPC64LE with non-Swift code?

Hi @belkadan, apologies, however I am quite new to Swift. 🙂

Is there a way to find if TSan work on PowerPC64LE with non-Swift code?

TSan (Thread Sanitizer) is an LLVM/Clang feature that you can read about here: https://clang.llvm.org/docs/ThreadSanitizer.html. I wouldn't take that list of supported platforms too seriously, though; that doc looks pretty old. You'll have to look around to find out.

Hi @belkadan

In the link mentioned by you, I checked link under section "More Information" - https://github.com/google/sanitizers/wiki/ThreadSanitizerCppManual

Supported Platforms:
TSan is supported on Linux x86_64, tested on Ubuntu 12.04.

I will disable this for PowerPC64LE and test further.
