[PATCH 1/2] ppc: Fix compiler warning in ptrace.c [-Wno-array-bounds]
The trick used to bypass the thread_struct fpr array in order to access the struct fpscr, in arch/powerpc/kernel/ptrace.c, can trigger an array subscript is above array bounds [-Werror=array-bounds] warning. Add -Wno-array-bounds to CFLAGS_ptrace.o, in arch/powerpc/kernel/Makefile to slience this warning.

Andreas. I resent the patch, with $(call cc-option) to check if GCC supports the option. Is it ok?
