This might be, need to test.

amd64 is new and TLS is probably not activated enabled in binutils yet.

i386 assebmly thing: what do you mean?

% cat test.c 
       .section ".tdata","awT", at progbits
foo:    .long   25
        .text
        movl    %gs:0, %eax
        leal    foo at TLSGD(,%ebx,1), %eax
        leal    foo at TLSLDM(%ebx), %eax
        leal    foo at DTPOFF(%eax), %edx
        movl    foo at GOTTPOFF(%ebx), %eax
        subl    foo at GOTTPOFF(%ebx), %eax
        addl    foo at GOTNTPOFF(%ebx), %eax
        movl    foo at INDNTPOFF, %eax
        movl    $foo at TPOFF, %eax
        subl    $foo at TPOFF, %eax
        leal    foo at NTPOFF(%ecx), %eax
