Notes for gcc-9-cross-ports - reproducible builds result

Version annotated: 27
Identified issues:
Identifier: blacklisted_on_jenkins
Description Some packages have been blacklisted in our test infrastructure because
their build hangs, takes too long, spawns processes that are not killed, or
simply because they use too many resources for our current capacity. (This
is purely practical step - we would like to test these packages.)
 

Our notes about issues affecting packages are stored in notes.git and are targeted at packages in Debian in 'unstable/amd64' (unless they say otherwise).
