Subject: [PATCH] tools build: Output more data during feature detection
Date: Fri, 18 Dec 2015 10:56:51 +0000	[thread overview]
Message-ID: <1450436211-170447-1-git-send-email-wangnan0@huawei.com> (raw)
In-Reply-To: <5673C8A6.1080806@bmw-carit.de>

Even with current '.make.output' finding the root cause for missing
feature is not enough. This patch adds extra information to
.make.output. It also creates a .make.makeoutput to collect output of
'make'.
