I believe make targets get run during jprt build process and then RE will
create a full build. After that, I take RE build and run tests. So, I  
running tests with slightly different option is not necessarily a problem -
rather I would think it confirm stability/quality of the tests!  
Moreover, at
least in theory, jtreg option itself should not alter test output 
(except test
failure with resource/logistical issues such as memory, timeout,  etc.. ).

Assuming jtreg options are managed to avoid logistical issues, any failure
probably indicates requirement of manual intervention to check whether
any improvement possibility in test or product.

There were 22 (excluding jdk_awt and jdk_swing) targets, and were 
running ~3600 tests combined.
But, I see some changes in Makefile targets since my last try.  I will 
rerun and see how many tests it
will run.
