The more recent versions of portageq have a command like that:

portageq envvar ENVNAME

However, I'd advise *against* using it.  The main reason why you shouldn't
query ENVNAME's like this is what you want to know might not be environment
variables in a future version of portage, or their name/meaning might change, 
etc.

As for distdir, I added a "distdir" option to portageq.  It'll be available in
the next portage release.
