AIX 5.3 has not been supported since OpenJDK8. Refer to https://wiki.openjdk.java.net/display/Build/Supported+Build+Platforms.
The currently used xlc 16.1 (XL C/C++ Compilers) also needs AIX 7.1, see http://www-01.ibm.com/support/docview.wss?uid=swg21326972.
So we should adjust the minimum OS version check done in os_aix.cpp in os::Aix::initialize_os_info().
