A friend of mine used to have a parrot......not sure of the species.
It learned to roar like a lion, quite convincingly and quite loudly, I might 
add.

So, faculatively, it is possible with at least one group of living birds.  But 
obligatory roaring?
 Who knows?


BTW:  When avian vocalization is discussed here, I always like to point the 
reader to:

http://www.birds.cornell.edu/brp/raven/RavenOverview.html

for free sound analysis software.

BTW part 2:  Have any researchers tried scaling up an avian vocalization 
structure to that of one on a T. rex?
