[oe] exo build fail - undefined macro

[Adam Lee]

Good afternoon!
On OE/Poky master branch, I am getting this error while building an XFCE
image. My layers have built ok on Dora.

My manifest<https://github.com/gumstix/Gumstix-YoctoProject-Repo/blob/dev/default.xml>
Full error <http://paste.ubuntu.com/7127725/>

Interesting thing is that I can build exo package individually. I only get
this error while building my xfce image.

Thank you,

Adam
