Subject: [PATCH 3/5] scripts/gdb: do not descend into scripts/gdb from scripts
Date:   Tue, 19 Feb 2019 18:33:04 +0900
Message-Id: <1550568787-18710-3-git-send-email-yamada.masahiro@socionext.com>
In-Reply-To: <1550568787-18710-1-git-send-email-yamada.masahiro@socionext.com>
References: <1550568787-18710-1-git-send-email-yamada.masahiro@socionext.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Currently, Kbuild descends from scripts/Makefile to scripts/gdb/Makefile
just for creating symbolic links, but it does not need to do it so early.

Merge the two descending paths to simplify the code.
