fix native package compile error with gcc 4.3.4 on x86 host

Add an option `-march' to BUILD_CFLAGS, GCC 4.3.4 on x86 host needs this option to let the atomic operations ("lock free") be available while it is used to compile glib-2.0-native

It's a bad idea to modify bitbake.conf to add option -march to BUILD_CFLAGS, because it's global and its side effect is unknown, such as beecrypt-native do_compile will fail if we do that.

So it's best to test most of the native recipes to have a check about the similar problem and fix them separately. The glib-2.0-native and qemu-native need to be fixed.
