Your patch includes the top-level configure patches. Those need to go
to GCC first; I'll take care of adding both aarch64 and mips at the
same time.

The ChangeLog entries shouldn't have "gold/" in the filenames.

+#define TARGET_TCB_SIZE ((size / 8) * 2)

I'm uncomfortable having a file-scope macro that refers to a template
parameter. Can't you just have a static const int TCB_SIZE in
Target_aarch64, and refer to it from the Output_data_got_aarch64 class
as Target_aarch64<size, big_endian::TCB_SIZE?

+  unsigned int
+  tcb_size() const { return this->tcb_size_; }

You can just return This::TCB_SIZE here (with a suitable typedef for This).

+  // Size of TCB
+  const unsigned int tcb_size_;

And this field can go away.

This is OK with the above changes. Thanks!
