The loongson 3A cores do not select a suitable -march option so the build system uses the default one from the toolchain. This may or may not be suitable for a loongson 3A build. In order to avoid that, we explicitly set a suitable -march option for that core. Cc: Huacai Chen <chenhc@xxxxxxxxxx> Cc: Maciej W.
