Note the rather more elaborate text-processing convolutions in the
definition of DATESTAMP_s and DEVPHASE_s.  $(shell) is necessary
there, and having been used there it makes sense to use it everywhere.

:= might make sense, but it seemed to me that it would be better to do
this lazily so that make invocations that never referred to these
variables did not need to read the files.  (What one really wants is
'evaluate this no more than once'...)
