RFR(S): JDK-8150197: Integrate AIX fixes from build-infra

[Volker Simonis]

Hi,

can I please have a reviewer and sponsor for this AIX build change:

http://cr.openjdk.java.net/~simonis/webrevs/2016/8150197/
https://bugs.openjdk.java.net/browse/JDK-8150197

The change is actually a downport from build-infra and it has already
been informally reviewed by Magnus in that repository.
The change itself updates the AIX link flags and uses a new option
during linking which produces a so called "loadmap". That's a file
which summarizes the link step and can be used to quickly detect
linking problems. The option has been already used for the HotSpot
build and will now be used for every shared library.

Thank you and best regards,
Volker
