is this code still relevant?
#if defined(_MSC_VER)
// MSVC's call_once implementation worked since VS 2015, which is the minimum
// supported version as of this writing.
#define LLVM_THREADING_USE_STD_CALL_ONCE 1
#elif defined(LLVM_ON_UNIX) &&
\
(defined(_LIBCPP_VERSION) ||

// std::call_once from libc++ is used on all Unix platforms. Other
// implementations like libstdc++ are known to have problems on NetBSD,
// OpenBSD and PowerPC.
#define LLVM_THREADING_USE_STD_CALL_ONCE 1
#elif defined(LLVM_ON_UNIX) &&
\
((defined(__ppc__) || defined(__PPC__)) && defined(__LITTLE_ENDIAN__))

#else
#define LLVM_THREADING_USE_STD_CALL_ONCE 0
#endif
Seems like something that's probably aged out? Check with @brad since it's from
