Subject: [PATCH 0/4] build: minimize rebuilds
Date: Tue, 26 Dec 2017 19:32:36 +0100	[thread overview]
Message-ID: <20171226183236.GA26708@ravnborg.org> (raw)

Following patchset minimizes re-builds.
With the setup I use at the moment where I run
build tests on 100+ arm related boards I see that the
build time is reduced to half - for an otherwise
clean build with no changes.
In other words - the wall clock time for a
simple "try to build all boards" where nothing
has changed goes from ~2:35 minutes to 1:21 minutes

The patches has been tested in my local setup - and
no missing rebuilds was seen.

      build: fix that defaultenv is always rebuilt
      build: fix that passwd.h is always built
      build: fix that the bbenv file is always rebuilt
      build: fix that LZO file is always rebuilt
