It looks that your assembler doesn't support AVX, so a fallback is triggered in
config/x86/x86_avx.cc:
#ifdef HAVE_AS_AVX
...
#define OUTPUT(T) _ITM_TYPE_##T
#define INPUT(T,X) , _ITM_TYPE_##T X
#else
...
#define OUTPUT(T) void
#define INPUT(T,X)
#endif
#define ITM_READ_MEMCPY(T, LSMOD, TARGET, M2) \
OUTPUT(T) ITM_REGPARM _ITM_##LSMOD##T (const _ITM_TYPE_##T *ptr) \
...
The problem is, that declarations in libitm.h do not agree with this:
#define ITM_BARRIERS(T) \
extern _ITM_TYPE_##T _ITM_R##T(const _ITM_TYPE_##T *) ITM_REGPARM; \
extern _ITM_TYPE_##T _ITM_RaR##T(const _ITM_TYPE_##T *) ITM_REGPARM; \
extern _ITM_TYPE_##T _ITM_RaW##T(const _ITM_TYPE_##T *) ITM_REGPARM; \
extern _ITM_TYPE_##T _ITM_RfW##T(const _ITM_TYPE_##T *) ITM_REGPARM; \
...
