So 'i386' is really the original name that stuck.
'x86-32' sounds more appropriate to me - we should not perpetuate the i386 name,
as we don't run on an original i386 anymore ;-)
Here's what I think sounds pretty natural:
- CONFIG_X86_X32_ABI and CONFIG_X86_32_ABI selects CONFIG_COMPAT.
- CONFIG_X86_32_ABI enables the 32-bit/32-bit system call ABI.
- CONFIG_X86_X32_ABI enables the extra 64-bit/32-bit system call entries.
- CONFIG_IA32_EMULATION goes away.

Yes, of course.
