+From 1c41d751d57a598919c40ab9c27514a98da93273 Mon Sep 17 00:00:00 2001
+From: "Robin H. Johnson" <robbat2@gentoo.org>
+Date: Sat, 31 Oct 2009 07:59:57 +0000
+Subject: [PATCH] set noexec markers in the asm file directly
+
+Using -Wl,-z,noexecstack can hide real exec stack issues coming from other
+files, and is a bit unportable.  Instead, set proper section markers in the
+assembly files directly.  It also means people using the static libraries
+won't have to use -Wl,-z,noexecstack when they link their code.
