Subject: [RFC kvm-unit-tests PATCH 5/8] Makefile: add explicit mkdir for .o targets
Date: Thu,  6 Apr 2017 20:07:24 +0100	[thread overview]
Message-ID: <20170406190727.5624-6-alex.bennee@linaro.org> (raw)
In-Reply-To: <20170406190727.5624-1-alex.bennee@linaro.org>

This is fairly direct way of ensuring the target build directories are
created before we build a binary blob. mkdir -p fails gracefully if
the directory is already there.
