Yeah, we could certainly fix (or extend?) kconfig to allow those 
forms too, if you would like to use them.

I personally prefer 'make ARCH=i386 defconfig' and 'make ARCH=x86_64 
defconfig' because it's a nice conceptual equivalent to:

	make ARCH=arm defconfig
	make ARCH=mips defconfig

et al.

'make ARCH=x86 defconfig' should probably default to the host bitness 
version, or always default to 64-bit - right now it defaults to 
i386_defconfig.

[ Note that some of the architectures are a bit weird there: for 
  example 'make ARCH=powerpc' will only work if you use a PPC 
  cross-compiler - but it generally works fine and i rely on that for 
  cross-build tooling. ]

As for your fix patch, is the wording i provided fine to you so i can 
commit it? I think we should treat it differently from any defconfig 
related fixes/enhancements and not delay it - the 2 years of delay 
was already too long IMHO! ;-)

Thanks,

	Ingo
