We just ran into an issue where tar failed to build on one server setup
but built everywhere else just fine.
It was running makeinfo to regenerate some docs files and makeinfo was too
old for the host it was running on. There was no dependency on makeinfo-native
as it was not meant to be regenerating the docs.
It was being regenerated as a date from a timestamp used in the docs
was different in Asian timezones than in the other timezones our builds
were being tested in.
I added an entry to https://wiki.yoctoproject.org/wiki/TipsAndTricks/
about how this was debugged.
As such, lets default to setting and exporting TZ to 'UTC' as was already
pioneered by the reproducibile builds work. This makes the builds
deterministic.

Export environmental variables needed for binary reproducibility with consistent values.
This class can be used either directly via:
INHERIT += "reproducible_build_simple"
or can be inherited by a more complex/complete bbclass, for example a bblass which
will crack SOURCE_DATE_EPOCH for each recipe.
