makefile

[hari krishna angadi]

hi all,
         i have problem in makefile.for each flags(test case).if i try to 
insmod i 
        test1.ko,test.ko,test3.ko i am gettiing the TC= -D_TEST3 for all  
       modules.
       if i insmod  test1.ko  i should get TC =-D_TEST1
      for  test2.ko TC = -D_TEST2 .....
    based on the flag my program will execute
            module ex:my makefile
       
        EXTRA_CFLAGS = -  -D_TEST1  
        test1-objs = module.o functions.o
        obj-m += test1.o
     make -C /lib/modules/$(shell uname -r)/build M=$(PWD) modules
        
    EXTRA_CFLAGS =   -D_TEST2
      make -C /lib/modules/$(shell uname -r)/build M=$(PWD) modules
     test2-objs = module.o functions.0
         obj-m += test2.o

     EXTRA_CFLAGS =   -D_TEST3
    make -C /lib/modules/$(shell uname -r)/build M=$(PWD) modules
   test3-objs = module.o functions.o
         obj-m += test3.o
