[PATCH] ppc64: remove hidden -fno-omit-frame-pointer for schedule.c

While looking at code generated by gcc4.0 I noticed some functions still
had frame pointers, even after we stopped ppc64 from defining
CONFIG_FRAME_POINTER.  It turns out kernel/Makefile hardwires
-fno-omit-frame-pointer on when compiling schedule.c.

Create CONFIG_SCHED_NO_NO_OMIT_FRAME_POINTER and define it on architectures
that dont require frame pointers in sched.c code.

(akpm: blame me for the name)
