#862112: r-base-dev: Generate reproducible output independently of the build path

[Holger Levsen]

Hi Dirk,

I've asked Ximin to file this bug so that we have something to track and to
refer in discussions…

Dirk, could you please point out (here in this bug report) which of the two parts
you consider unsuitable?

Ximin, looking at https://anonscm.debian.org/cgit/reproducible/r-base.git/log/?h=pu/reproducible_builds
I believe it would be best to merge those two (top most) commits into one?

actually we've been using Ximin's patches on tests.reproducible-builds.org
since the 2nd of May on amd64 and since the 3rd on arm64, armhf and i386.

According to https://tests.reproducible-builds.org/debian/index_performance.html
(top row labeled "oldest build result) in the first table on the right) this
means we've almost done a full rebuild with the patch on amd64+arm64 (probably
85% done now) and pretty close to that on i386…

According to this, this patch seems to work well…
