Hello, please review this small AIX – specific change .

Currently we use by default the bundled zlib (= zlib coming with OpenJDK) on Windows, on other platforms the system zlib.

However it is possible to switch to the bundled zlib in the configure process .

We had some build issues on AIX build systems with ancient system-zlibs , so I propose to use as default the bundled zlib on AIX too .

(would also mean that we use a current 1.2.11 in the build on AIX which is not bad, on some AIX machines I’ve seen older zlibs)

Bug/webrev :

Thanks, Matthias
