The buildroot kernel configure/make is called with the correct 'ARCH=i386' and
uses the kernel i386_defconfig without further specification of CPU type, which
defaults from the linux kernel configure (see e.g.
build/linux-5.11/arch/x86/Kconfig.cpu) to M686:

        prompt "Processor family"
        default M686 if X86_32
        default GENERIC_CPU if X86_64

For workaround specify the correct CPU either by configuring a custom linux
kernel config/defconfig file (or configure by 'make linux-menuconfig')...

Maybe something which can be improved in buildroot..., on the other side a very
special use-case ;-)
