Normally, the symbols in the freshly built object file that create-diff-object used are the same with our original module. But the name of the symbols may change if use --skip-gcc-check or the influence of KCFLAGS. This patch compile original module for create-diff-object, like original vmlinux, to detect this problem earlier, before we need to insmod klp.ko.
