From e4d33a4e488fb7abfa41b5ff947d048d22d000f4 Mon Sep 17 00:00:00 2001
From: Jaco Kroon <jaco@uls.co.za>
Date: Mon, 7 Nov 2022 17:30:00 +0200
Subject: [PATCH] Build system: Avoid executable stack.
Found in res_geolocation, but I believe others may have similar issues,
thus not linking to a specific issue.
Essentially gcc doesn't mark the stack for being non-executable unless
it's compiling the source, this informs ld via gcc to mark the object as
not requiring an executable stack (which a binary blob obviously
doesn't).
