From mboxrd@z Thu Jan 1 00:00:00 1970 From: Yann E. MORIN Date: Wed, 7 Mar 2018 21:27:18 +0100 Subject: [Buildroot] [PATCH 1/2] spport/check-bin-arch: accept arbitrary ignore paths In-Reply-To: References: Message-ID: <8a08e5fbfab7e4d021565077544576ad495c8097.1520454419.git.yann.morin.1998@free.fr> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: buildroot@busybox.net Some packages (mostly, out-of-tree) may want to install binary blobs for another architecture, outside the locations we currently exclude, like in /opt or whatever... Add support in check-bin-arch to accept any arbitrary location, that individual package can each request to excude from the check, when they are installed. Signed-off-by: "Yann E.
