The reason for parallel make failing to build the help pages is that
the executable isn't listed as a dependency of the htmlcmd target, so
make may attempt to build the HTML files before the executable has
been built.

With the rule:

	cmd: $(BIN)/$(PGM) htmlcmd

you can't assume that the two dependencies will be built sequentially;
a parallel make will try to build them in parallel. The htmlcmd target
needs to have the program listed as an explicit dependency, e.g.:

	htmlcmd: $(BIN)/$(PGM)
