I don't think there is enough information left for ld.so to fix the situation.

With local dynamic the relocations in test.so are

Relocation section '.rela.dyn' at offset 0x2a8 contains 1 entries:
  Offset          Info           Type           Sym. Value    Sym. Name +
Addend
000000200ff0  000000000010 R_X86_64_DTPMOD64                    0

Relocation section '.rela.plt' at offset 0x2c0 contains 1 entries:
  Offset          Info           Type           Sym. Value    Sym. Name +
Addend
000000201018  000100000007 R_X86_64_JUMP_SLO 0000000000000000 __tls_get_addr +
0

So it will always get variable in test.so.
