Hi!
While working on the "reproducible builds" effort [1], we have noticed
that hoichess could not be built reproducibly.
The list of object files is unsorted, which causes a non-deterministic
linking order.
The attached patch fixes this.
Regards,
Reiner

Hi, this patch is not working anymore unfortunately (the new upstream changed
the Makefile and the patch doesn't apply
anymore)
I see amd64 seems fixed now, but armhf and i386 aren't.
I think this might be due to a bug in the toolchain rather than a bug in the
software, and I'm closing this one.
Unfortunately I have no skills to check these dbg differences
