[RESEND PATCH 1/2] ppc: Fix compiler warning in ptrace.c [-Wno-array-bounds]

[Stratos Psomadakis]

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.
