RFA: Add unlink-if-ordinary to 4.0's libiberty

[Nick Clifton]

Hi Guys,

  I am seeking approval to apply the attached patch.  It is not a
  regression fix however, so it may well be denied.

  The patch imports the unlink-if-ordinary() function into libiberty
  from the mainline GCC sources.

  The motivation for this patch is that the about-to-be-released 2.16
  binutils branch uses this function (in bfd/cache.c) and it would be
  nice if the 2.16 binutils and 4.0 gcc sources were compatible with
  each other.  This is the only patch necessary for that
  compatibility.

  May I apply the patch ?

Cheers
  Nick
