Great to see this changed to agentvm mode and thanks for adding the 
CONCURRENCY variable which I think will be much more useful than gmake -j.

One thing in the Makefile is that it defaults to jtreg 4.0 when JT_HOME 
isn't set and I think you need 4.1 to get agentvm mode.

Also shouldn't you also s/SAMEVM/AGENTVM/ so that there are no longer 
any references to samevm?
