Source: bazel-bootstrap Version: 4.2.3+ds-4 Severity: normal 4.2.3+ds-3 actually built on mips64el: https://buildd.debian.org/status/logs.php?pkg=bazel-bootstrap&arch=mips64el
Instead of a manually defined list of 64bit architectures, a build dependency on architecture-is-64-bit (provided by architecture-properties in bookworm) would achieve the same.
