Can you be more specific about what your distro.conf file says? I'm
guessing you're requiring poky.conf in there? Are you setting the value
after the require and does it work if you do it beforehand?

I ask as that variable is used in a require in poky.conf, effectively
causing an immediate expansion of the variable so it needs to be set
before poky.conf, not afterwards.

Cheers,
