Here is the script I used to do the build:

    git clone http://git.yoctoproject.org/git/poky

    cd poky
    git checkout -b rocko-rzn1 yocto-2.4.3
    git am ${RELEASE_DIR}/yocto/rocko/0001-ARM-Add-Cortex-A7-vfpv4-d16*.patch
    cd ..
    
    git clone -b rocko git://git.openembedded.org/meta-openembedded
    git clone https://github.com/cmhe/meta-readonly-rootfs-overlay.git
    git clone -b rocko https://github.com/renesas-rz/meta-rzn1.git
    
    cd poky
    source oe-init-build-env
    cp ${RELDIR}/yocto/bblayers.conf  build/conf/bblayers.conf
    cp ${RELDIR}/yocto/local.conf     build/conf/local.conf
    bitbake core-image-minimal
    bitbake meta-toolchain

The core images (kernel, device tree, and rootfs) seem to be OK.

bblayers.conf:

    # POKY_BBLAYERS_CONF_VERSION is increased each time build/conf/bblayers.conf
    # changes incompatibly
    POKY_BBLAYERS_CONF_VERSION = "2"
    
    BBPATH = "${TOPDIR}"
    BSPPATH := "${@os.path.abspath(os.path.dirname(d.getVar('FILE',True)) + '/../..')}"

local.conf:

    #
    # This file is your local configuration file and is where all local user settings
    # are placed. The comments in this file give some guide to the options a new user
    # to the system might want to change but pretty much any configuration option can
    # be set in this file. More adventurous users can look at local.conf.extended
    # which contains other examples of configuration which can be placed in this file
    # but new users likely won't need any of them initially.
    #
    # Lines starting with the '#' character are commented out and in some cases the
    # default values are provided as comments to show people example syntax. Enabling
    # the option is a question of removing the # character and making any change to the
    # variable as required.
    
    #
    # Machine Selection
    #
    # You need to select a specific machine to target the build with. There are a selection
    # of emulated machines available which can boot and run in the QEMU emulator:
    #
    #MACHINE ?= "qemuarm"
    #MACHINE ?= "qemuarm64"
    #MACHINE ?= "qemumips"
    #MACHINE ?= "qemumips64"
    #MACHINE ?= "qemuppc"
    #MACHINE ?= "qemux86"
    #MACHINE ?= "qemux86-64"
    #
    # There are also the following hardware board target machines included for 
    # demonstration purposes:
    #
    #MACHINE ?= "beaglebone"
    #MACHINE ?= "genericx86"
    #MACHINE ?= "genericx86-64"
    #MACHINE ?= "mpc8315e-rdb"
    #MACHINE ?= "edgerouter"
    #
    # This sets the default machine to be qemux86 if no other machine is selected:
    MACHINE ??= "qemux86"
    
    #
    # Where to place downloads
    #
    # During a first build the system will download many different source code tarballs
    # from various upstream projects. This can take a while, particularly if your network
    # connection is slow. These are all stored in DL_DIR. When wiping and rebuilding you
    # can preserve this directory to speed up this part of subsequent builds. This directory
    # is safe to share between multiple builds on the same machine too.
    #
    # The default is a downloads directory under TOPDIR which is the build directory.
    #
    DL_DIR ?= "${TOPDIR}/downloads"
    
    #
    # Where to place shared-state files
    #
    # BitBake has the capability to accelerate builds based on previously built output.
    # This is done using "shared state" files which can be thought of as cache objects
    # and this option determines where those files are placed.
    #
    # You can wipe out TMPDIR leaving this directory intact and the build would regenerate
    # from these files if no changes were made to the configuration. If changes were made
    # to the configuration, only shared state files where the state was still valid would
    # be used (done using checksums).
    #
    # The default is a sstate-cache directory under TOPDIR.
    #
    #SSTATE_DIR ?= "${TOPDIR}/sstate-cache"
    
    #
    # Where to place the build output
    #
    # This option specifies where the bulk of the building work should be done and
    # where BitBake should place its temporary files and output. Keep in mind that
    # this includes the extraction and compilation of many applications and the toolchain
    # which can use Gigabytes of hard disk space.
    #
    # The default is a tmp directory under TOPDIR.
    #
    #TMPDIR = "${TOPDIR}/tmp"
    
    #
    # Default policy config
    #
    # The distribution setting controls which policy settings are used as defaults.
    # The default value is fine for general Yocto project use, at least initially.
    # Ultimately when creating custom policy, people will likely end up subclassing 
    # these defaults.
    #
    DISTRO ?= "poky"
    # As an example of a subclass there is a "bleeding" edge policy configuration
    # where many versions are set to the absolute latest code from the upstream 
    # source control systems. This is just mentioned here as an example, its not
    # useful to most new users.
    # DISTRO ?= "poky-bleeding"
    
    #
    # Package Management configuration
    #
    # This variable lists which packaging formats to enable. Multiple package backends
    # can be enabled at once and the first item listed in the variable will be used
    # to generate the root filesystems.
    # Options are:
    #  - 'package_deb' for debian style deb files
    #  - 'package_ipk' for ipk files are used by opkg (a debian style embedded package manager)
    #  - 'package_rpm' for rpm style packages
    # E.g.: PACKAGE_CLASSES ?= "package_rpm package_deb package_ipk"
    # We default to rpm:
    PACKAGE_CLASSES ?= "package_rpm"
    
    #
    # SDK target architecture
    #
    # This variable specifies the architecture to build SDK items for and means
    # you can build the SDK packages for architectures other than the machine you are
    # running the build on (i.e. building i686 packages on an x86_64 host).
    # Supported values are i686 and x86_64
    #SDKMACHINE ?= "i686"
    
    #
    # Extra image configuration defaults
    #
    # The EXTRA_IMAGE_FEATURES variable allows extra packages to be added to the generated
    # images. Some of these options are added to certain image types automatically. The
    # variable can contain the following options:
    #  "dbg-pkgs"       - add -dbg packages for all installed packages
    #                     (adds symbol information for debugging/profiling)
    #  "dev-pkgs"       - add -dev packages for all installed packages
    #                     (useful if you want to develop against libs in the image)
    #  "ptest-pkgs"     - add -ptest packages for all ptest-enabled packages
    #                     (useful if you want to run the package test suites)
    #  "tools-sdk"      - add development tools (gcc, make, pkgconfig etc.)
    #  "tools-debug"    - add debugging tools (gdb, strace)
    #  "eclipse-debug"  - add Eclipse remote debugging support
    #  "tools-profile"  - add profiling tools (oprofile, lttng, valgrind)
    #  "tools-testapps" - add useful testing tools (ts_print, aplay, arecord etc.)
    #  "debug-tweaks"   - make an image suitable for development
    #                     e.g. ssh root access has a blank password
    # There are other application targets that can be used here too, see
    # meta/classes/image.bbclass and meta/classes/core-image.bbclass for more details.

    #
    # Additional image features

    # are:
    #   - 'buildstats' collect build statistics
    #   - 'image-mklibs' to reduce shared library files size for an image
    #   - 'image-prelink' in order to prelink the filesystem image
    #   - 'image-swab' to perform host system intrusion detection

    # further details.

    # Interactive shell configuration
    #
    # Under certain circumstances the system may need input from you and to do this it
    # can launch an interactive shell. It needs to do this since the build is
    # multithreaded and needs to be able to handle the case where more than one parallel
    # process may require the user's attention. The default is iterate over the available
    # terminal types to find one that works.
    #
    # Examples of the occasions this may happen are when resolving patches which cannot
    # be applied, to use the devshell or the kernel menuconfig
    #
    # Supported values are auto, gnome, xfce, rxvt, screen, konsole (KDE 3.x only), none

    # shutdown the build. If there is less that 100MB or 1K inodes, perform a hard abort
    # of the build. The reason for this is that running completely out of space can corrupt
    # files and damages the build in ways which may not be easily recoverable.
    # It's necesary to monitor /tmp, if there is no space left the build will fail
    # with very exotic errors.
