    Remove dead code in config/rs6000/vxworks.h
    
    These lines were added last year:
    
    /* Initialize library function table.  */
     #undef TARGET_INIT_LIBFUNCS
     #define TARGET_INIT_LIBFUNCS rs6000_vxworks_init_libfuncs
    
    but TARGET_INIT_LIBFUNCS is #undef-ed in config/rs6000/rs6000.c and
    rs6000_vxworks_init_libfuncs is nowhere defined in any case.
    
    gcc/
            * config/rs6000/vxworks.h (TARGET_INIT_LIBFUNCS): Delete.
