prims.cc (_Jv_Abort): Always print error message using fprintf, don't try to allocate.

        * prims.cc (_Jv_Abort): Always print error message using fprintf,
        don't try to allocate.
        (_Jv_CreateJavaVM): Set gcj::runTimeInitialized.
        * include/jvm.h (gcj::runTimeInitialized): New variable declaration.
        * java/lang/natClassLoader.cc (_Jv_RegisterClassHookDefault): Handle
