add binary which has a single R_X86_64_TPOFF64 relocation

```C
// libfootls.c
__thread int foo_tls = 42;
```

```C
// ext_tls.c
extern __thread int foo_tls;
int main() {
    return foo_tls;
}
```

```bash
gcc -c -Wall -Werror -fpic libfootls.c
gcc -shared -o libfootls.so libfootls.o

gcc -L./ -Wl,-rpath=./ -Wall -o ext_tls ext_tls.c -lfootls
$ ./ext_tls
```
