Check for KALLSYMS

Browse Source 
Check at ./configure time that the kernel was built with kallsyms
support.  If the kernel doesn't have CONFIG_KALLSYMS defined the
modules will still compile cleanly but will not be loadable.  So
we really want to catch this early during ./configure.  Note that
we do not require CONFIG_KALLSYMS_ALL but it may be safely defined.
