Looking at those pastebins, it shows up as a python function since the
"python" flag is set. That shouldn't do anything too bad to the variable
though:

python PACKAGECONFIG () {
}

In one case it has the value python, in the other it does not. Its all
very odd. I wonder if "bitbake -e" shows it taking any value? There has
to be something in the Angstrom setup which is triggering this...

Cheers,
