KBuild fails while compiling without debugging flag - c

Question

I am trying to compile a very simple module, but it fails to create *.ko when i am not adding -g flag. Here is the source code:
#include <linux/init.h>
#include <linux/module.h>
static int simple_test_init(void){
printk(KERN_INFO "Hello Kernel!");
return 0;
}
static void simple_test_exit(void){
printk(KERN_INFO "Goodbye Kernel!");
}
MODULE_LICENSE("GPL");
MODULE_DESCRIPTION("Simple test module");
module_init(simple_test_init);
module_exit(simple_test_exit);
And here is GCC/Makefile.
KBUILD_CFLAGS := -Werror -fcf-protection=branch
obj-m += test.o
all:
make -C /lib/modules/$(shell uname -r)/build M=$(PWD) modules
clean:
make -C /lib/modules/$(shell uname -r)/build M=$(PWD) clean
And finally the output of GCC.
make -C /lib/modules/5.19.3-arch1-1/build M=/test modules
make[1]: Entering directory '/usr/lib/modules/5.19.3-arch1-1/build'
