[yocto] bsp doc bug

[Frans Meulenbroeks]

I was trying to create a bsp layer. In the doc I bumped into the
following example for layer.conf:

# We have a conf directory, add to BBPATH
BBPATH := "${BBPATH}${LAYERDIR}"

[...]

Isn't there a colon mssing here.
If I look at the layer.conf of meta-ememlow it does have a colon:

BBPATH := "${BBPATH}:${LAYERDIR}"

Guess this is a typo in the doc (both html and pdf have this)
