Subject: [PATCH 1/4] bitbake.conf: use := for BUILD_OS and BUILD_ARCH
Date: Thu, 27 May 2010 14:16:25 -0700	[thread overview]
Message-ID: <1274994988-5750-1-git-send-email-clarson@kergoth.com> (raw)

From: Chris Larson <chris_larson@mentor.com>

These don't change, so their initial values should be just fine.  Apparently,
in a typical build, those os.uname() snippets are called around 46k times,
which seems a tad excessive :)
