go writes build-specific ids into binaries it produces
and has a custom system for calculating them from
file hashes, environment variables and other inputs
(not that dissimilar to sstate cache, actually). This can
go wrong :) in various ways (for purposes of reproducibility
in particular), so this enables useful logs to see what
happens and why.
