This patch introduces HAVE_NORMAL_FRAME_POINTER Kconfig symbol. When
defined, the top level Makefile won't add -fno-omit-frame-pointer
cflag (the flag is useless for PowerPC kernels, and also makes gcc
generate wrong code).

+	select HAVE_NORMAL_FRAME_POINTER

+config HAVE_NORMAL_FRAME_POINTER
+	bool
+	help
+	  Architectures should select this symbol if their ABI implies
+	  having a frame pointer.

I am totally confused what you call a frame pointer here.
None of the relevant PowerPC ABIs have a frame pointer
separate from the stack pointer; the compiler can create
one, of course.  A better config symbol name and help text
would help understand this patch :-)
