It'd be useful to hear from some concrete embedded target users, whether they customize `-msmall-data-limit=`, whether they are happy with `-msmall-data-limit=8`, or whether they are just unaware this threshold.

If an embedded system typically customizes compiler driver options a lot, I think they can consider adding `-msmall-data-limit=` (with a value suitable for their use cases) in a configuration file <https://clang.llvm.org/docs/UsersManual.html#configuration-files>, not letting their use cases judge Linux systems.
