Bug#792625: multiarch = same and different date-entries in generated man page of i32/i64

[Roelof Berg]

I had a look at the idea of writing manpages manually (as upstream) and 
unfortunately saw some difficulties: Because OpenBSD and Linux use 
different *roff syntax, man vs. mdoc, if I understodd it correctly, 
generating the man pages in the syntax of the actual operating system 
would be the most  portable way (everyone: correct me if I'm wrong). I 
don't want to favor Linux or BSD or Windows (just kidding :) in the 
source tarball.

Defining SOURCE_DATE_EPOCH and using the latest help2man version did 
_not_ fix the date on my system. Even worse: I'm also using doxygen for 
the man page of the library, which isn't capable of using 
SOURCE_DATE_EPOCH anyway. So SOURCE_DATE_EPOCH doesn't seem to be the 
right direction for me.

I'm thinking of rude stuff now: Patching the manpages after generation 
with my own script, taking the date based on dpkg-parsechangelog as 
input. Maybe it's possible with SED.

I can't be the first one facing this issues, right ? Thanks for the 
excellent feedback so far.
