[PATCH] ppc32: fix compilation error in arch/ppc/kernel/time.c

make defconfig give the following error on ppc (gcc-4):

arch/ppc/kernel/time.c:92: error: static declaration of ‘time_offset’
follows non-static declaration
include/linux/timex.h:236: error: previous declaration of ‘time_offset’
was here

The following patch solves it (time_offset is declared in timer.c).
