Because without it running the build in the 32bit chroot will get the 
initial reported issue:


$ uname -m
i686
$ make oldconfig
scripts/kconfig/conf  --oldconfig Kconfig
*
* Restart config...
*
*
* Linux/x86 4.17.0 Kernel Configuration
*
64-bit kernel (64BIT) [Y/n/?] (NEW)


which breaks our buildbots running in chroots...


Now I can work around it by adding the config bit myself, but I'd like 
to understand what changed and why...
