I got some undefined references to __stack_chk_fail in
arch/powerpc/boot/stdio.o and arch/powerpc/boot/prom.o when I was trying
to build a kernel on Ubuntu Edgy Eft - which includes Stack Smashing
Protection.
This patch adds -fno-stack-protector to BOOTCFLAGS in
arch/powerpc/boot/Makefile (why does BOOTCFLAGS depend on HOSTCFLAGS and
not CFLAGS?).
Regards,
Niels Kristian Bech Jensen
