The test case works for me on armv5tel-linux-gnueabi with gcc 4.4, 4.5, and
4.6.
Comparing your assemby code with mine I see that your calls
__emutls_get_address while mine calls __aeabi_read_tp, and the section
allocation for .LANCHOR0 is different (your is in .bss, mine is in .section
.tdata,"awT",%progbits).

So I suspect the issue is dependent on emutls or uclibc.
