I don't think there's really any documentation besides reading the code.

It appears to be bailing out because edje requires lua and it's not
being found. Probably $? != 0 and possibly you would see this
executing pkg-config with --print-errors.

Arguably pkg-config should not be trying to resolve dependencies when
you're just doing --variable and not --libs or something. I don't know
if there's any history behind that decision. I'm traveling right now,
so I don't have a chance to look at the code right this second. Maybe
Tollef can chime in, though.
