sim/ppc: Fix linker error with -fno-common
GCC 10 enables -fno-common by default. This resulted in a multiple definition linker error since global variables were declared and defined in a header file: ld: ld-insn.o:sim/ppc/ld-insn.h:221: multiple definition of `max_model_fields_len'; igen.o:sim/ppc/ld-insn.h:221: first defined here sim/ppc * ld-insn.h (last_model, last_model_data, last_model_function, last_model_internal, last_model_macro, last_model_static): Delete. (max_model_fields_len, model_data, model_functions, model_internal, model_macros, model_static, models): Declare, but do not define. * ld-insn.c (last_model, last_model_data, last_model_function, last_model_internal, last_model_macro, last_model_static, max_model_fields_len, model_data, model_functions, model_internal, model_macros, model_static, models): Define.
