Subject: [PATCH 3/5] tools build feature: Introduce feature_ass macro
Date: Wed, 23 Dec 2015 18:58:32 +0100 [thread overview]
Message-ID: <1450893514-9158-4-git-send-email-jolsa@kernel.org> (raw)
In-Reply-To: <1450893514-9158-1-git-send-email-jolsa@kernel.org>
The feature_ass macro generates feature value
assignment for name, like:
$(call feature_ass,dwarf) == feature-dwarf=1
This will be used more in following patches.
