ARM: 9382/1: ftrace: Define ftrace_stub_graph 



Several architectures defines this stub for the graph tracer,
and it is needed for CFI, as it needs a separate symbol for it.
The trick from include/asm-generic/vmlinux.lds.h to define
ftrace_stub_graph to ftrace_stub isn't working when using CFI.
Commit 883bbbff contains the details.
