Appropriate values for gitversion, gitdate when building RPM packages

[Nick Urbanik]

Dear Team,

Inspired by Dave Witbrodt's success in getting free ATI drivers
working with his HD 5750 described here:

I am building some RPM packages to make my wife and son's iMac 27-inch
machines finally work with free ATI drivers too.

How do you determine the appropriate gitversion and gitdate values
with the result of a git clone?
