Add option -march to BUILD_CFLAGS in order to let the atomic operations ("lock free") be available while using old version GCC (4.3.4 for example) on x86 host to compile glib-2.0-native.

Hi Colin,

I have a fully test and the qemu-native has the similar problem, and I will resend the patch.

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, and the packagegroup-toolset-native.bb could work for that.

Regards,
Hongxu
