While investigating avrdude for reproducible builds in FreeBSD I found that the only nonreproducibility is the "Compiled on" string:

Debian has a patch to just remove the timestamps:
http://sources.debian.net/src/avrdude/6.3-1/debian/patches/no-cpp-timestamps.patch/

Discussed with Joerg which resulted in this suggestion:

>
> Well, that timestamp is somehow meaningful for people who

> I agree it's pointless for a released version.
>
> I'd like to come up with some kind of autoconf magic that

> non-released software.


Filing here as an enhancement request.
Joerg suggested instead having some sort of autoconf switch to set a "release build" mode
