Some of our specialized sections are not prefixed with the conventional period. The compiler uses input section names to derive certain other section names (e.g. `.rela.text`, `.relacpu_ops`), and these can be difficult to select in linker scripts when there is a lack of a delimiter. This change introduces the period prefix to all specialized section names. BREAKING-CHANGE: All input and output linker section names have been prefixed with the period character, e.g. `cpu_ops` -> `.cpu_ops`.
