[PATCH] kbuild: Unbreak cleaning external module build directory

[Bart Van Assche]

Avoid that "$(MAKE) -C $(KDIR) M=$(PWD) clean" triggers the following
error message when invoked from inside the Makefile of an external
kernel module:

rm: cannot remove 'System.map': Permission denied
make[1]: *** [clean] Error 1
