[meta-python,v4,1/6] python3-frozenlist: support reproducibility

In order to make the generated library be reproducible, build wheel
in source dir other than tmp dir (/tmp/xxxxxx), then yocto toolchain's
option -fdebug-prefix-map could work as expected

Note: To support reproducibility, it also requires oe-core commit [1] to be merged

This is worth submitting upstream.

Ooh I knew I remembered the frozenlist name from somewhere.

FWIW, there’s an upstream ticket for this issue: https://github.com/aio-libs/frozenlist/issues/577.  And I filed https://github.com/aio-libs/yarl/issues/1551 which is related.

I agree with Khem. This is worth submitting upstream. Also, I would
STRONGLY advise we stop using “Pending”. Let us do the work to do an MVP
submission upstream and point to that. ANY kind of messaging upstream is a
step towards the right direction. The reason is we actually tend to never
follow through and submit. This will begin to bite us with the new world of
CRA.
