Native installers - provide a way to build a 32bit installer with 64bit JDK (and vice versa)

With the current JDK classes, libraries and executables for installer creation it is not possible to create a 32bit installer with a 64bit JDK (and vice versa).

This is a problem for following use case:
Creating two installers (32bit AND 64bit) within only one execution (e.g. Maven release) is not possible, because Maven will run either with a 32bit or 64bit JDK for both installer creations.

This issue is maybe related to RT-22994 (maybe this issu here is kind of sub-feature).
