[PATCH] Add coreutils/unlink.c

  unlink is not the only nonconforming executable in GNU coreutils.
true and false, for instance, also accept GNU options. (Because
being able to perform "true --help" and "true --version" is vital.)
It's just a symptom of GNU's tendency to think itself as better than
the standard while pretending to conform to it.

  Busybox has to make a choice: either be conformant or mimic GNU
coreutils' behaviour. Both paths are valid, but Busybox has to be
consistent with it: all utilities have to make the same choice.

  I vote for a general compile-time option BB_MIMIC_GNU, if there
isn't anything similar already.
