Change from V2: as Khem Raj suggested, use `-march=native' to cause the
compiler to auto-detect the architecture of the build computer, if the
auto-detect is unsuccessful the option has no effect.
When compile glib-2.0-native and qemu-native with with gcc 4.3.4 on x86 host
,it
needs to add `-march' to CFLAGS, because the GCC needs this option to let the
atomic operations ("lock free") be available.
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.
