[PATCH 0/2]native recipes:add option march to BUILD_CFLAGS

[Hongxu Jia]

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

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.

Did you mean to say glib?

I mean using old version GCC(4.3.4 for example) on x86 host to compile
glib-2.0-native.
