  25 /* NAME is a name without slashes, as it appears in a DT_NEEDED entry
  26    or a dlopen call's argument or suchlike.  NAMELEN is (strlen (NAME) + 1).
  27
  28    Find NAME in an OS-dependent fashion, and return its "real" name.
  29    Optionally fill in *FD with a file descriptor open on that file (or
  30    else leave its initial value of -1).  The return value is a new
  31    malloc'd string, which will be free'd by the caller.  If NAME is
  32    resolved to an actual file that can be opened, then the return
  33    value should name that file (and if *FD was not set, then a normal
  34    __open call on that string will be made).  If *FD was set by some
  35    other means than a normal open and there is no "real" name to use,
  36    then __strdup (NAME) is fine (modulo error checking).  */
