I'm experimenting with a special target that touches
a state file to force an upstream object to be treated
as out of date if its source file is local.  This may
require a gmake "two-step": gmake checklocal ; gmake 
(or internally reinvoke).

I have a prototype that isn't generic, but seems to
do the job and I am attempting to generalize it.
