Provide a stub for within_module() when CONFIG_MODULES is not set. This
is needed to build CONFIG_GCOV_KERNEL.

The above commit got backed out of the -mm tree, due to the issue this
patch addresses, so not sure it provides the correct context for the
patch. Maybe that line in the commit message should be dropped?

Do folks think that similar stubs for within_module_core and
within_module_init should be added, while we're here?
It looks like kernel/trace/ftrace.c uses them, but has proper
CONFIG_MODULE guards.
