Make system should detect changes to primitves.cfg and libraries.cfg

[nispio]

Running xmbld with automatically switch over to using the mmake system if MidasMakefile exists. One of the implications is that xmbld will ignore changes to primitives.cfg and libraries.cfg. This seems like a very unintuitive result.

At a minimum, the make system should warn if primitives/libraries.cfg are newer than MidasMakefile. Possibly it should update the makefile to incorporate the changes. This is obviously fraught, because the MidasMakefile may be much more up-to-date, and updating primitives.cfg could then reverse all of the changes.
