kernel/kernel-arch: Explicitly mapping between i386/x86_64 and x86 for kernel ARCH
For a bare-bone kernel recipe which specifies 32 bit x86 target,
a 64 bit .config will be generated from do_configure task when
building 32-bit qemux86, once all of these conditions are true:
* arch of host is x86_64
* kernel source tree used in build has commit
ffee0de41 which
actually chooses i386 or x86_64 defconfig by asking host when
ARCH is "x86" (arch/x86/Makefile)
* bare-bone kernel recipe inherits directly from kernel without
other special treatments.
Build will fail because of the mismatched kernel architecture.
The patch sets ARCH i386 or x86_64 explicitly to configure
task to avoid this host contamination. Kernel artifact is also
changed so that it can map i386 and x64 back to arch/x86 when
needed.
