  i really hate replying to my own posts because i forgot to do
something basic, but i did a quick grep:

$ grep -r "BBPATH :=" *
documentation/dev-manual/dev-manual-common-tasks.xml:     BBPATH := "${LAYERDIR}:${BBPATH}"
documentation/dev-manual/dev-manual-kernel-appendix.xml:     BBPATH := "${BBPATH}:${LAYERDIR}"
documentation/bsp-guide/bsp.xml:     BBPATH := "${BBPATH}:${LAYERDIR}"
meta-hob/conf/layer.conf:BBPATH := "${BBPATH}:${LAYERDIR}"
meta-skeleton/conf/layer.conf:BBPATH := "${BBPATH}:${LAYERDIR}"
meta-yocto/conf/layer.conf:BBPATH := "${LAYERDIR}:${BBPATH}"
$

  so there's a mixture of that ordering.  if there's no real reason
for that, it should really be consistent so readers don't wonder about
it.
