Bug#710266: gcc-4.8: fails to build current git head kernel x86-64 architecture

[Arthur Marsh <arthur.marsh@internode.on.net>]

Package: gcc-4.8
Version: 4.8.0-8
Followup-For: Bug #710266

I tried building the kernel with:

MAKEFLAGS="CC=gcc-4.8 LD=ld.gold CFLAGS=-save-temps=obj" \
make-kpkg --config menuconfig --initrd linux-image

which finished with:

  CC      arch/x86/boot/compressed/misc.o
/tmp/ccP2VYLr.s: Assembler messages:
/tmp/ccP2VYLr.s:1187: Error: expecting string instruction after `rep'

What CFLAGS setting(s) should I use to keep the needed intermediate files
and what resulting intermediate files would you need?
