Subject: [PATCH v2] x86: suppress "Nothing to be done for ..." messages

When we compiled again, arch/x86/syscalls/Makefile and
arch/x86/tools/Makefile emitted "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 those fixes, "all" and "relocs" should be added to PHONY.

x86/build: Supress "Nothing to be done for ..." messages

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.
