This is an insane expectation. This is kernel convention (it has
nothing to do with uml):

SUBARCH := $(shell uname -m | sed -e s/i.86/x86/ -e s/x86_64/x86/ \
 -e s/sun4u/sparc64/ \
 -e s/arm.*/arm/ -e s/sa110/arm/ \
 -e s/s390x/s390/ -e s/parisc64/parisc/ \
 -e s/ppc.*/powerpc/ -e s/mips.*/mips/ \
 -e s/sh[234].*/sh/ -e s/aarch64.*/arm64/ )

config 64BIT
bool "64-bit kernel" if ARCH = "x86"
default ARCH != "i386"
---help---
 Say yes to build a 64-bit kernel - formerly known as x86_64
 Say no to build a 32-bit kernel - formerly known as i386

If you want to stand on your head and demand that all these
conventions be changed against all reason, I have nothing further to
say.
