Bug#660857: owfs: FTBFS(kfreebsd): libow.so: undefined reference to `w1_bind'

[Vincent Danjean]

  Hi Paul,

  There has been a debian bug report ( http://bugs.debian.org/660857 )
about failure during compilation on kfreebsd (see at the end of this
mail).
  I think that the problem is that ow_com_open.c, at lines 53,
calls w1_bind without checking the OW_W1 is set. Can you confirm
my diagnostic? I propose the patch in attachment that revert to
the previous behavior (as in p13) if OW_W1 is not defined, ie
an error with debug message "Unimplemented"

  Regards,
    Vincent
