--- Comment #1 from H.J. Lu <hjl.tools at gmail dot com> ---
This may be a glibc bug.  With glibc 2.23, I got

[hjl@gnu-6 tls-gnu2-1]$ cat def.c 
__thread int gd = 1;
[hjl@gnu-6 tls-gnu2-1]$ cat gd.c
extern __thread int gd;

int *
get_gd (void)
{
  return &gd;
}

void
set_gd (int i)
{
  gd = i;
}

int
test_gd (int i)
{
  return gd == i;
}
[hjl@gnu-6 tls-gnu2-1]$ cat ld.c
static __thread int ld;

int *
get_ld (void)
{
  return &ld;
}

void
set_ld (int i)
{
  ld = i;
}

int
test_ld (int i)
{
  return ld == i;
}
[hjl@gnu-6 tls-gnu2-1]$ cat main.c
#include <stdio.h>
#include <stdlib.h>

extern int * get_gd (void);
extern void set_gd (int);
extern int test_gd (int);
extern int * get_ld (void);
extern void set_ld (int);
extern int test_ld (int);

int
main ()
{
  int *p;

  p = get_gd ();
  set_gd (3);
  if (*p != 3 || !test_gd (3))
    abort ();

  p = get_ld ();
  set_ld (4);
  if (*p != 4 || !test_ld (4))
    abort ();

  printf ("PASS\n");

  return 0;
}
