[PATCH 3/3] accel/tcg: Remove special case for GCC < 4.6


From: Philippe Mathieu-Daudé
Subject: [PATCH 3/3] accel/tcg: Remove special case for GCC < 4.6
Date: Mon, 28 Sep 2020 14:58:59 +0200

Since commit efc6c070aca ("configure: Add a test for the
minimum compiler version") the minimum compiler version
required for GCC is 4.8.

We can safely remove the special case for GCC 4.6 introduced
in commit 0448f5f8b81 ("cpu-exec: Fix compiler warning
(-Werror=clobbered)").
No change for Clang as we don't know.
