From 6262e4e74e2cdb9f231dc71c9893d4a4bd1e88df Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Mon, 25 Apr 2011 08:06:40 +0000 Subject: [PATCH] disable security warning flags when possible Some toolchains enable security warning flags by default, but these don't really make sense in the u-boot world. Such as forcing changes like: -printf(foo); +printf("%s", foo); So disable the flags when the compiler supports them. Linux has already merged a similar change in their build system.
