Hello,

I've investigated non-determinism in our linux-libre package, which
sadly appears to have regressed in that regard since I last looked into
it 3 years ago (see commit 01ea70a29c5c1ded31c37ce8c43192bc1956b2ca
("gnu: linux-libre: Make build reproducible.")).

I'm currently seeing these differing files:

Toggle snippet (7 lines)

I'll take a look at what Yocto does differently, if anything.
