If no one has a better idea.  This might help in a lot of cases.  Just
do a genlop -t <package name> and look at how long it took to complete. 
You take that qtwebengine package that takes so long to compile as a
example. If it spits out a time of a few minutes, that was a binary.  If
it is a long time, close to a hour or more, then it compiled it.  That
should work for the larger packages anyway.  Unless you have a really
fast CPU.

Also, don't forget equery u <package name> will display USE flags for
what is installed and what will be changed, if anything is changed. 
There may be a way to change what it looks at too.  I never went deeper
than what is installed and what it will install next. 

I hope someone has a much better answer tho.  I'm not 100% sure of what
you looking for.  I think I got a idea but I could be missing
something.  I'm working on cutting up that tree again and my back just
threw up a white flag.  My brain is somewhat divided at the moment.  One
part is trying to type, the other is letting me know my back is plenty
angry.  :/   I'm beating that tree tho.  Only got a log about 15 feet
long left.  Two more cuts.
