Okay I will send out a patch that modifies libsanitizer/configure.ac and
libsanitizer/tsan/Makefile.am that will separate out tsan_rtl_amd64.S from
getting build for other targets.

 // The trick is that the call preserves all registers and the compiler
 // does not treat it as a call.
 // If it does not work for you, use normal call.

+#if defined(__x86_64__) && TSAN_DEBUG == 0

This change is also acceptable?
