You might want to read the latest status update to learn about them:
https://lists.debian.org/debian-devel/2015/08/msg00443.html

But they are not the source of reproducibility, just a symptom.

From the quick look I had, it seems symbols are sorted in a different
order depending on the locale:
https://reproducible.debian.net/dbd/unstable/amd64/littler_0.3.0-2.debbindiff.html#r-cran-littler_0.3.0-2_amd64.deb/data.tar.xz/data.tar/./usr/bin/r/objdump%20--disassemble%20--full-contents%20{}
(It's my guess because both are sorted by the second build has lowercase
'a' grouped together with uppercase 'A'.)

The symbols match the ones in
https://sources.debian.net/src/r-base/3.2.2-1/src/library/datasets/data/

Hope that helps,
