+ * The optimization portion of the build system has been reworked to avoid
+   broken builds on certain architectures.  All architecture-specific
+   optimization has been removed in favor of using -march=native to allow gcc
+   to detect the environment in which it is running when possible.  This can
+   be toggled as BUILD_NATIVE under "Compiler Flags" in menuselect.
