building in 32bit chroot on x86_64 host broken (was: Linux 4.17)

I have a 32bit x86 and a 64bit x86_64 install on the system.
With linux source up to 4.16.x I could do:
setarch i686 (or use command linux32)
chroot /path/to/32bit/
(/dev, /proc, /sys, /run is bind mounted in the chroot)
Then I could build a 32bit kernel in the chroot without booting the
32bit system...
(host is running a 4.14 longterm kernel)
but building from 4.17 source in the chroot I get:
$ 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)
So it does not pick up 32bit anymore ...
Is this intentional ? If so, why ? If not, how can I fix it ?
