RFR 8081770 [TESTBUG] regression Test7107135 needs to remove dependence on locally installed gcc

[Chris Plummer]

Hi Jerry,

Thanks for taking care of this. As Calvin pointed out in the other 
review, you should be using "hg rename".

Otherwise overall your changes look fine, but I'm a little uncertain 
about one aspect of your changes, and if it might impact the nature of 
the testing. The shell script used LD_LIBRARY_PATH to make the jni 
libraries locatable. Your java version uses -Djava.library.path. I think 
this is probably ok, but just want to point it out and make sure.

thanks,

Chris
