fix(coverity): build all configs before exiting

Bailing out immediately after a failure obscures other errors, which
inevitably appear on future coverity runs. Ensure all configurations are
built and report the last non-normal exit status. The script will fail as
before, but this ensures all errors in the tree are visible.
