Not running Linux on my laptop at the moment, so I cannot check the svn
but as I see it, you want to be able to copy the linux image to

1) BINARIES_DIR
2) root file system (option)
3) A place where it is easy to download to the target using tftp,
    which defaults to "/tftpboot".
    It is OK, to make this programmable as long the default is used.
    As an option, we could add a shell symbol "BUILDROOT_TFTP_DIR"
    which overrides the menuconfig.
