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 arch if
ARCH is "x86" (arch/x86/Makefile)
() bare-bone kernel recipe inherits directly from kernel without
other special treatment
Build will fail in this case because of the mismatched architecture
of kernel image after compiling.
The patch sets ARCH i386 or x86_64 explicitly to configure
task to avoid this host contamination.
