Subject: [PATCH] perf tools: Fix tags target rebuilding
Date: Tue, 26 Nov 2013 12:21:30 +0100
Message-Id: <1385464890-19876-1-git-send-email-jolsa@redhat.com>
Sender: linux-kernel-owner@vger.kernel.org
List-ID: <linux-kernel.vger.kernel.org>
X-Mailing-List: linux-kernel@vger.kernel.org

Once the tags file is generated it's never rebuilt
until it's removed by hand.

The reason is that the Makefile does not treat tags
as a target but as a file to be rebuilt.

Adding tags as PHONY target into the Makefile.
