kbuild: fix infinite make recursion
Jan Engelhardt <jengelh@computergmbh.de> reported: You can cause a recursion in kbuild/make with the following: make O=$PWD kernel/time.o make mrproper Of course no one would use O=$PWD (that's just the testcase), but this happened too often: /ws/linux/linux-2.6.23$ make O=/ws/linux/linux-2.6.23 kernel/time.o (Oops - should have been O=/ws/linux/obj-2.6.23!) Fixed by an explicit test for this case - we error out if output directory and source directory are the same.
