    KBuild: silence "'scripts/unifdef' is up to date." · e1b702cf

    While changing our build system over to use the headers_install target
    as part of our klibc build, the following message started showing up in
    our logs:
    make[2]: `scripts/unifdef' is up to date.
    It turns out that the build blindly invokes a recursive make on this
    target, which causes make to emit this message when the target is
    already up to date.  This isn't seen for most targets as the rest of the
    build relies primarily on the default target and on PHONY targets when
    invoking make recursively.
    Silence the above message when building unifdef as part of
    headers_install by hiding it behind a new PHONY target called
    "build_unifdef" that has an empty recipe.
