Indeed it's strange.
I've just re-tested it and still see root login working perfectly.

I'm on mainline/master branch with my patch applied (no other changes):
--->---
(my patch) 7af7de3 system: run getty on boot console by default
f7add51 qemu: add host/target Linux version check
--->---

And this is output of "make savedefconfig":
--->---
BR2_x86_pentiumpro=y
BR2_KERNEL_HEADERS_VERSION=y
BR2_DEFAULT_KERNEL_VERSION="3.18"
BR2_PACKAGE_HOST_LINUX_HEADERS_CUSTOM_3_18=y
BR2_LINUX_KERNEL=y
BR2_LINUX_KERNEL_CUSTOM_VERSION=y
BR2_LINUX_KERNEL_CUSTOM_VERSION_VALUE="3.18"
BR2_LINUX_KERNEL_USE_CUSTOM_CONFIG=y
BR2_LINUX_KERNEL_CUSTOM_CONFIG_FILE="board/qemu/x86/linux-3.18.config"
BR2_TARGET_ROOTFS_EXT2=y
# BR2_TARGET_ROOTFS_TAR is not set
--->---

Note that this is based on "qemu_x86_defconfig" and with my patch
applied that's why you don't see mention of "console".

You may try even without my patch and manually set
BR2_TARGET_GENERIC_GETTY_PORT=console
