Subject: [PATCH v6 7/8] kbuild: build sample modules along with the rest of the kernel

Make sample modules in parallel with the rest of the kernel rather
than having them built from the vmlinux target. This makes the build
slightly faster, and those modules are properly considered when
adjust_autoksyms.sh is executed.
