If available, provide a link back to Gerrit on the overview page of a build. Uses the default style (i.e. style unset), which makes it non-intrusive visually.

# This file defines the static Buildkite pipeline which attempts to
|
|
# create the dynamic pipeline of all depot targets.
|
|
#
|
|
# If something fails during the creation of the pipeline, the fallback
|
|
# is executed instead which will simply report an error to Gerrit.
