Subject: Ubuntu 16.10 - Linux Kernel build fails - GCC related

After upgrading to Ubuntu 16.10, I can't build kernels anymore unless
the following patch is applied to the kernel Makefile. A word of
caution for anybody that is planning to update their development
systems.

https://patchwork.ozlabs.org/patch/616621/

Please refer to the Ubuntu 16.10 release notes for more details.

https://wiki.ubuntu.com/YakketyYak/ReleaseNotes#GCC

Ubuntu is recommended applying this patch for building Linux kernels.
I am not sure this is the right way to go. I am hoping this is
work-around and patching the kernel Makefile will not be the solution
going forward.

I haven't seen any patch sent upstream to make this change, so I still
hope this is a temporary work-around. Maybe be there is patch that
came through and you are aware of this problem?

thanks,
