[PATCH V2 0/2]fix native package compile error with gcc 4.3.4 on x86 host

[Hongxu Jia]

Change from V1: rebase to commit f9b894eaba94763a8ec790f8635f58b4e7e05381

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.
