[yocto] is there really an "INITRD_IMAGE" variable?

  it looks like there was a shift from INITRD_IMAGE to one of
INITRD_IMAGE_VM or INITRD_IMAGE_LIVE on feb 24, 2016 in this commit in
oe-core:

    syslinux.bbclass: make vm and live can be built together

    * The vm image(hdddirect, vmdk, qcow2, vdi) and live image (hddimg, iso)
      couldn't be built together because the following vars settings are
      conflicted:
      - SYSLINUX_ROOT (/dev/sda2 vs /dev/ram0)
      - LABELS (boot vs boot install)
      - INITRD (None vs live install)
      - SYSLINUX_CFG (see above)
      Introduce new vars (SYSLINUX_ROOT_VM/_LIVE, the samilar to others) to
      make them can work together, now we can build all of them together:

      IMAGE_FSTYPES += "live iso hddimg hdddirect vmdk qcow2 vdi"

    * Use SYSLINUX_CFG rather than SYSLINUXCFG to keep align with others
      SYSLINUX vars.

    * The SYSLINUX_TIMEOUT had been set, but it didn't work since
      AUTO_SYSLINUXMENU wasn't set, this would cause confusions, so also set
      AUTO_SYSLINUXMENU.

    * Move SYSLINUX_PROMPT and SYSLINUX_TIMEOUT to syslinux.bbclass rather
      than in separate classes since they are the same.

    * Set SYSLINUX_TIMEOUT to 50 to have a unique timeout for syslinux.

and i guess someone just didn't notice the remaining references to
INITRD_IMAGE.
