RFR(xs): 8204935: [aix] TOC overflow in libjvm.so (release build)

Hi all, may I have reviews for this small build fix: Bug: https://bugs.openjdk.java.net/browse/JDK-8204935 webrev: http://cr.openjdk.java.net/~stuefe/webrevs/8204935-aix-toc-overflow/webrev.0... We finally have reached the point where even the standard (not gtest) release build libjvm.so got too large and blew its TOC. Hurray for templates. On the bright side, no need to keep different flags for different libjvm variants anymore. Kudos to whoever added auto-automake to the build, that makes these kind of changes really easier :) Thank you, Best Regards, Thomas
