With -D, non-existent input files are not written to the .d file.  This
can cause confusing failures in some complex situations where one
substitution is pulled into a second substitution.

Title:
  msi -D reports errors if template file is not found

Status in EPICS Base:
  Confirmed

Bug description:
  This results in non-fatal but ugly and confusing error messages during
  generation of the dependency files (e.g. xxx.db.d), if a substitution
  file depends on a template file that is generated. Typical output:

  msi: Can't open file 'ErrHistBufString.template'
  input: '' at 
  make[2]: *** Deleting file 'MachineProtectionDebug.MPSCX33GF.db.d'

  In this case ErrHistBufString.template is a generated file. The error
  message only appears after a make clean.

  I think msi -D should behave similar to gcc -M -MG. Quoting from the
  man page,

    -MG In conjunction with an option such as -M requesting dependency generation, -MG assumes
        missing header files are generated files and adds them to the dependency list without
        raising an error. The dependency filename is taken directly from the "#include" directive
        without prepending any path.
