[PATCH/AARCH64] Fix TLS for ILP32

[Andrew Pinski]

Hi,
  In ILP32, the thread control block is 2 pointers or 4 byte in size.
This patch fixes the code so that it uses the correct offset for the
TLS variables.

OK?  Built and tested on aarch64-linux-gnu with no regressions.

Thanks,
Andrew

ChangeLog:
* elfnn-aarch64.c (TCB_SIZE): Base on the ARCH_SIZE rather than a
fixed size of 16.
