Subject: [PATCH] init/version.c: Define version_string only if
	CONFIG_KALLSYMS is not defined.

int Version_* is only used with ksymoops, which is only needed (according to
README and Documentation/Changes) if CONFIG_KALLSYMS is NOT defined.  Therefore
this patch defines version_string only if CONFIG_KALLSYMS is not defined.
