Log Message:
make(1): do not create empty shell files in jobs mode
In a chain of dependencies such as "all: build; build: do-build", the
intermediate targets do not have any commands. In jobs mode,
nevertheless, an empty file was created and fed to the shell. This was
unnecessary. See jobs-empty-commands.mk.
The case of the special command line "...", which was suggested on
current-users, is not optimized since it doesn't occur in practice.
