Use of OPENWIN_HOME on linux

[David Holmes]

Thanks Chris. I had just this minute come to the realization that the 
JDK6 code is the code that changed, while JDK7 has the original code. 
Those CRs are somewhat lacking in detail, but cross-compilation is 
exactly why this needs to be settable.

I'm working on the SE-Embedded merge with JDK7, so I can make the change 
as part of that work, to support cross-compilation. Just wanted to get a 
better understanding of why things were the way they are before I 
started making changes.

Cheers,
David
