linux-base: Mapping between i386/x86_64 and x86 for kernel ARCH

The patch (from meta, branch master, commit c0e9f2d)
sets ARCH i386 or x86_64 explicitly to configure task
to avoid this host contamination. So kernel configuration step
is also changed so that it can map i386 and x64 back to arch/x86.
