Patch adding Wii support by tueidj, part 8: system-specific changes

- conditionally compiles out some code intended for the PC platforms
- compat.c: get home directory routine, access() implementation
- game.c: don't use ioctl(), lower cache1d size to 8 MiB, Wii-specific
  initialization code and application directory ("apps/eduke32")
