Which is apparently what KCONFIG_ALLCONFIG already does? It doesn't work 
for choices, but it's still fine for setting/clearing CONFIG_64BIT.
 
We'll want to make it simpler to use - so you really can do something like
   make CONFIG_64BIT=n randconfig
   make CONFIG_64BIT=n allmodconfig
   make CONFIG_64BIT=y CONFIG_SATA_MV=y oldconfig
etc. without having to create a text file. But that's not hard. A simple 
implementation might just *make* a file with the options on the command 
line and point KCONFIG_ALLCONFIG at it to start with, although there are 
probably cleaner ways to implement it.

And then this legacy trick of using the obsolete $ARCH settings to 
override the setting of CONFIG_64BIT can be deprecated.
