           Summary: [4.9 Regression] lib64/libtsan.so: undefined reference
                    to `sigsetjmp'

           Version: 4.9.0
            Status: UNCONFIRMED

looks like it is not possible to use -fsanitize=thread with current trunk.

> cat test.c
int main()
{
 return 0;
}

> gcc  -fsanitize=thread -pie -fPIC test.c
