-adjust for new libs, programs and source files
-replace generated config.h and mkver
-add Frederick Bruckman's awk implementation of "ntptrace" as a
replacement for the perl program in the original tree
* Don't bother prefixing commands with a line of ${_MKCMD}\
and instead rely upon "make -s". This is less intrusive on
all the Makefiles than the former. Idea from David Laight.
* Rename the variables use to print messages. The scheme now is:
_MKMSG_FOO Run _MKMSG 'foo'
_MKTARGET_FOO Run _MKMSG_FOO ${.TARGET}
From discussion with Alistair Crooks.
+ 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.
