Building 32-bit on 64-bit Linux without jprt.config?

jprt.config is used by our internal build/test system so I don't know 
why your changes were made there. Anyway the main changes would be in 
the top-level makefiles (possibly top-level of each sub-repository).

I've only done this for hotspot and then in an older version of the 
system. But the basic approach, as I recall, was to emulate the solaris 
approach and just make sure if LP=64 (or equivalent) is not set then use 
all the necessary 32-bit flags.

Ironically my changes were not applied to the JPRT side of things :) - yet.
