    rs6000: Incorporate new builtins code into the build machinery
    
    2020-07-26  Bill Schmidt  <wschmidt@linux.ibm.com>
    
            * config.gcc (powerpc*-*-*): Add rs6000-builtins.o to extra_objs.
            * config/rs6000/t-rs6000 (rs6000-gen-builtins.o): New target.
            (rbtree.o): Likewise.
            (rs6000-gen-builtins): Likewise.
            (rs6000-builtins.c): Likewise.
            (rs6000-builtins.o): Likewise.
            (rs6000-call.o): Add dependency on rs6000-builtins.c.
