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.
