From 26cb9d81e0dff472f3da338ab8b2de1cd77676a7 Mon Sep 17 00:00:00 2001
From: Mathieu Desnoyers <mathieu.desnoyers@efficios.com>
Date: Sun, 24 Nov 2013 03:31:44 -0500
Subject: [PATCH] Blacklist ARM gcc 4.8.0, 4.8.1, 4.8.2
It produces clobbered frame accesses, which can lead to stack corruption
when racing with signal handlers nested on stack.
