Hardcode man page dates to date of groff release (September 4, 2005
for 1.19.2 in this case).

We can not use mdate.sh since after checkout/update from version
control, it might be today's date and MKREPRO won't work.

- remove generated files
- remove libdriver dependencies where they are not needed
- add bin to Makefile

merge our changes and add build glue
