+ Make depend required all the source files to be built before
the dependencies were generated due to some sub-optimal logic
in the version generation.
Fix from Bernd Ernesti in private mail.
+ Make the version string contain ${PROG} as originally intended
and not "ntpd" for all 7 programs.
Also move version generation to Makefile.inc to stop having 7 copies
of exactly the same thing.
