Ah, this is just a cherry-pick (with fixing conflicts, updated Fixes
and removed the last paragraph) of 5y.o. 76366050eb1b ("x86/defconfigs:
Explicitly unset CONFIG_64BIT in i386_defconfig"), it should be standalone
patch. I borrowed the commit message.  So, whatever you prefer: I can send
it again as the original one, one of x86 maintainers can do themselves
the cherry-picking / conflict resolution, or I can resend it as mine.
