        This CR tracks infrastructure changes to the Hotspot source base that enables several features that improve the portability and flexibility when building Hotspot.

        o Enable the use of a BUILD_CLIENT_ONLY option that forces a client compiler only
        build of Hotspot. This is used when Hotspot is ported to a new architecture but only
        the Client JIT is implemented.

        o Add support for Cross compiling Hotspot. CROSS_COMPILE_ARCH when set to a target
        architecture will enable this feature.

        o Add Software Floating Point support for processors that do not contain an FPU.

        o This CR also contains code changes to support newer GCC versions, support for
        dynamically supporting headless JRE's and resolves a problem caused by a 4 second
        delay when UsePerfData is disabled.
