[BUILD] fix Makefile.bsd and Makefile.osx for stream_interface

Did a full compile of the 1.3.15.7 - 20081208 snapshot on Freebsd-7.x
recently, and noted that there needs to be a quick patch done on the
Makefile for bsd machines.

This was due to the stream_interface replacing the send data commands
in the rewrite Willy did a while ago.

Simple fix, and it compiled cleanly otherwise.  Thanks for the work
Willy!

Cheers,
  Ross.
