OPTIONS handling doesn't seem to work fully in dependencies anymore

John said (correct me if I'm wrong) that with an up-to-date system 
OPTIONS doesn't correctly shows up (when the top port has OPTIONS), but 
with an "old" system this worked. Reading the bsd.port.mk, the 
"incriminated" CONFIG_DONE rows never changed since the introduction of 
the OPTIONS support, so I think this *never* worked as expected.
