Hello Bernhard,
If you are interested in reproducible builds please have a look at this
patch series I submitted a while ago:
http://dpdk.org/dev/patchwork/patch/28386/
I have verified that those patches make the build reproducible on
Debian (x86/x86_64/arm64).
Feedback from SUSE is very welcome!

I am very interested in that topic.
and would like to see http://dpdk.org/dev/patchwork/patch/28387/ merged
(instead of my patch).
If https://savannah.gnu.org/bugs/?52076 gets merged, it will avoid the
need for the others, except the above and
http://dpdk.org/dev/patchwork/patch/28391/
The latter I have not found necessary so far, but races are hard to
reproduce anyway.

In case you want to have a look, the DPDK page on the Debian
reproducible builds CI is the following:
https://tests.reproducible-builds.org/debian/rb-pkg/unstable/amd64/dpdk.html
A new build in experimental is failing but it looks like it's due to a
different version of GCC being used between different builds.

That last one was tricky, I'd say it happens one out of ten builds.
Thanks for all your work, having the GNU Make wildcard sort out of the
box would be really great!
