This may be useful for some build environments to avoid parallel make
issues, and artificially-concocted order dependencies, leaving the ordering
up to that specified in the Makefile.
The related makedefs options are now:
‐s Generate the bogusmon , engrave and epitaph files.
‐1 Generate the epitaph file.
‐2 Generate the engrave file.
‐3 Generate the bogusmon file.
Also resolves an existing issue encountered in doc/makedefs.6 where "and epitaphfiles"
was being produced in the result.
