Via bug 391273, it is desirable to change to 64 bit architecture for hpux ia64, so several values need to change from "ia64_32" to simply "ia64". 

In some files, such as buildAll.xml this is best accomplished with a simple variable. In that file, we already have a "streamSpecificInit" task that reads 
streamSpecific-build.properties from the maps project. 

So, in master, we will have 

hpuxia64bitness=ia64

whereas for R3_maintenance and R4_2_maintenance we will have 

hpuxia64bitness=ia64_32

And then in several files, such as buildAll.xml and helper.xml where there is now "ia64_32" as a value, we'll simply have ${hpuxia64bitness}

This is easier/best for large central files, such as buildAll.xml, since only one main version to maintain, instead of two versions all due to a handful of differences. 

[But, other files, best handled by providing the whole file in a the "eclipseBuilderOverlay" directory, either out of necessity (e.g. the value is part of a target name, or similar) or ... just less risky.
