Hi all,

This is the 4.8 backport of the LINK_SPEC changes to pass down the 
linker option
--fix-cortex-a53-835769

Bootstrapped and tested on aarch64-none-linux-gnu.
This depends on the patches under review at:
https://gcc.gnu.org/ml/gcc-patches/2014-10/msg01757.html
and
https://gcc.gnu.org/ml/gcc-patches/2014-10/msg01758.html

Ok for that branch after the prerequisites go in?

Thanks,
Kyrill
