When we build an already built kernel again, arch/x86/syscalls/Makefile
and arch/x86/tools/Makefile emits "Nothing to be done for ..."
messages.
Here is the command log:
$ make defconfig
[ snip ]
$ make
[ snip ]
$ make
make[1]: Nothing to be done for `all'. <-----
make[1]: Nothing to be done for `relocs'. <-----
CHK include/config/kernel.release
CHK include/generated/uapi/linux/version.h
Besides not emitting those, "all" and "relocs" should be added to PHONY as well.
