Bug#978494: binutils-arm-none-eabi: reproducible builds: Enable deterministic archives

[Vagrant Cascadian]

Package: binutils-arm-none-eabi
Severity: normal
Tags: patch
User: reproducible-builds at lists.alioth.debian.org
Usertags: timestamps toolchain
Control: affects -1 libstdc++-arm-none-eabi
X-Debbugs-Cc: reproducible-bugs at lists.alioth.debian.org

binutils-arm-none-eabi is not built with deterministic archives enabled,
which causes reproducibility issues in packages using it:

  https://tests.reproducible-builds.org/debian/issues/unstable/timestamps_in_static_libraries_issue.html

The attached patch adds --enable-deterministic-archives to the configure
arguments in debian/rules.

FWIW, the --enable-deterministic-archives feature was enabled Debian's "binutils"
package in 2015.

With this feature enabled in binutils-arm-none-eabi, I've been able to
reproducibly build libstdc++-arm-none-eabi when using a stable build
path.
