Add this target in Makefile:
*_fmt_plug.c: Makefile john.c
true
This simply adds a junk target, to avoid the error. the 2 seds to create fmt_*.h files are still run. If there are no plugs, they simply create 0 byte files, but the error in the make is removed.
I have only tested on cygwin (with gnu make as the default make process). This may not be viable on things like sun make, etc.
