Subject: [PATCH v2 2/5] builddeb: set CC on cross build to prefixed gcc
Date: Wed, 26 May 2021 01:01:36 +0200	[thread overview]
Message-ID: <20210525230139.6165-3-bage@linutronix.de> (raw)
In-Reply-To: <20210525230139.6165-1-bage@linutronix.de>

From: Bastian Germann <bage@linutronix.de>

Building the generated package with CC unset will fail for cross
compilation. Detect that and set CC to a sane default prefixed by
dpkg-architecture's DEB_HOST_GNU_TYPE variable.
