The change will have to go in Modules/Platform/HP-UX.cmake.   I think we 
should be able to check the CMAKE_HOST_SYSTEM_PROCESSOR variable.   If 
someone has access to one of these machines and can work out a patch, I 
can put it in CMake.  Even better, if someone has access to one of these 
machines, and can setup a nightly dashboard to make sure it stays working.
