Maybe I spoke too soon...  It seems that make looks for other files that
are dependencies, but don't have explicit rules.  Like
include/autoconf.mk, config.mk, etc.  Linux has a number of implicit
rule overrides (search for implicit in its top-level Makefile) that
appear to be for the same type of issue.  This seems like a somewhat
hokey fix to have a number of empty rules defined though.  Any better
ideas or comments on why this issue didn't exist before?

Best,
Peter
