Pull up revision 1.21 (requested by lukem):
- in local), only run $0.local if it is an existing file
  (prevents spurious warning for mfs /dev, amongst other things)
- for mipsco, news68k, newsmips: ensure that "umask 77" is run after $0.local
- for playstation2: add local) target, and use in all)  (for consistency)
