RFR(S): 8197906: Enable CDS mode execution of jtreg tests via make

[Mikhailo Seledtsov]

Hi Igor,

   Thank you very much for catching this, and for the explanation. I 
have updated the patch and running tests now.
I assume the recommended update is small/trivial enough that it does not 
need another webrev; let me know otherwise.

Thank you,
Misha
