of line ignored

CND creates makefile that cannot be made on remote host in case latest 
Linux distribution.
Root causes of bug:

- CND uses java.io for creating sub-makefile. It makes not synchronized 
FO and disk file.
Remote file system in this case does not upload real sub-makefile.
Fix consist from two part:
- use "FO create data" instead java.io
- fix priority of shell command in makefile .PHONY target.
