I think I figured out the problem Don't worry about this for now.
I am trying to cross compile a simple Hello world program that I plan to upload as a module into an android ARM device. Below is the c code.
#include<linux/init.h>
#include <linux/module.h>
#include <linux/kernel.h>
MODULE_LICENSE("GPL");
MODULE_AUTHOR("CW");
MODULE_DESCRIPTION("Demo Hello");
static int init_module(void)
{
printk(KERN_ALERT "<1>Hello World\n");
return 0;
}
static void cleanup_module(void)
{
printk(KERN_ALERT "Good Bye World\n");
}
module_init(init_module);
module_exit(cleanup_module);
Below is the makefile.
VERSION = 3
PATCHLEVEL = 2
SUBLEVEL = 0
EXTRAVERSION = 00763-g4071679
obj-m :=hello.o
KDIR := /lib/modules/$(shell uname -r)/build
PWD := $(shell pwd)
default:
$(MAKE) ARCH=arm CROSS_COMPILE=/home/userid/rowboat-android/prebuilt/linux-x86/toolchain/arm-eabi-4.4.3/bin/arm-eabi- -C $(KDIR) SUBDIRS=$(PWD) modules
clean:

Below is the intial section of the error log
