Its unavoidable really, we have to have some host system we build on as
we need a compiler/headers from it. Even if you build a gcc-native,
what would you compile it with? :)

If you do want to avoid the risk, you'd choose your own custom base OS
(or container) and then always build on that. It would then be both
reproducible and deterministic. We don't want to mandate a specific
host configuration out the box though.

So this patch avoids an issue. We don't tend to run into too many
issues like this one thankfully.

Cheers,

Richard
