Fix ARCH=ppc builds

Fix ARCH=ppc builds

[Josh Boyer]

The recent signal rework broke ARCH=ppc builds with the following error:

CC      arch/powerpc/kernel/signal.o
arch/powerpc/kernel/signal.c: In function ‘do_signal’:
arch/powerpc/kernel/signal.c:142: error: implicit declaration of function ‘set_dabr’
make[1]: *** [arch/powerpc/kernel/signal.o] Error 1

The patch below fixes it by including a function prototype in
asm-ppc/system.h
