Unfortunate infinite make recursion

Hi,


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!)

The make O=$PWD truncates the Makefile, making it necessary to run `git
checkout Makefile` - should you have git; or reextract the tarball
(should you /still/ have it). Well, can we catch this case somehow?


thanks,
Jan
