[PATCH]Add aarch64 to list of targets that support gold

[Jing Yu]

Hi,

This patch changes top level configure to add aarch64 to list of
targets that support gold. Have tested binutils with this patch on
x86_64 and aarch64 platforms.
OK for trunk?


2014-09-18  Jing Yu  <jin...@google.com>
      * configure.ac: Add aarch64 to list of targets that support gold.
      * configure: Regenerate.

Thanks,
Jing
