Me neither, I guess it's no longer present. But perhaps you could add my short 
shell snippet above as a post-build test? Run it, sleep 2, run it again, it 
should give the same result.

I'm unable to reproduce this with 2.27.51.20161108-1.

I can confirm this. Minimal test case:

$ touch lol && ar cruv lol.a lol && xxd lol.a | head -n4
ar: `u' modifier ignored since `D' is the default (see `U')
r - lol
: 213c 6172 6368 3e0a 2f53 594d 3634 2f20  !./SYM64/ 
0010: 2020 2020 2020 2020 3134 3738 3732 3431  14787241
0020: 3239 2020 3020 2020 2020 3020 2020 2020  29  0 0 
0030: 3020 2020 2020 2020 3732 2020 2020 2020  0   72  

Watch the timestamp increase as you run this repeatedly. It doesn't happen with 
ar from binutils, only binutils-multiarch.

However, it looks like it might be an upstream issue - notice the explicit 
notice saying that `D' is supposedly the default, yet there's a timestamp 
there. So the Debian package is passing in the correct configure flag 
(--enable-deterministic-archives) but it's not being respected for some reason.
