I am not strictly opposed to your patch, but I think the problem should
be tackled elsewhere, so that fewer packages need to be modified.
Have you considered filing a wishlist bug against binutils to build with
"--enable-deterministic-archives", so that ar and ranlib operate in
deterministic mode by default? Also, what's the current state of
#759895?
