This is not possible today, it would require extended the
kconfig-package infrastructure a bit.

What you can do today (obviously), is generate this kernel
configuration, possibly by going in output/build/linux-4.11.3, save it
as a defconfig that you then tell Buildroot to use. Not ideal perhaps,
but it works :)

Best regards,
