Fix:

  hw/m68k/virt.c:263:13: error: declaration shadows a local variable [-Werror,-Wshadow]
            BOOTINFOSTR(param_ptr, BI_COMMAND_LINE,
            ^
  hw/m68k/bootinfo.h:47:13: note: expanded from macro 'BOOTINFOSTR'
        int i; \
            ^
  hw/m68k/virt.c:130:9: note: previous declaration is here
    int i;
        ^
