description:
Add .MAKE.META.BAILIWICK - to identify the scope of make's control.
meta_oodate: if a file that was written or linked within our bailiwick,
but outside of .OBJDIR is missing, add it to missingFiles.
If we get to the end of the .meta file without seeing it [re]moved,
then consider the target out-of-date.
