TARGET_ARCH is in fact not exported as you have indicated, there's this
piece in meta/conf/bitbake.conf:

  # Make sure TARGET_ARCH isn't exported
  # (breaks Makefiles using implicit rules, e.g. quilt, as GNU make has this
  # in them, undocumented)
  TARGET_ARCH[unexport] = "1"

HOST_ARCH defaults to TARGET_ARCH, I suppose it should be fine to use:

  HOST_ARCH = "${TARGET_ARCH}"
