Why do we need to modify make when what your asking for is easily
created by thoughtful makefile construction. If you preface your target
rules with a macro, say MKDBG, default setting it to "@" then you have a
silent build. When you need to bug on the command line just add "MKDBG="
and now all target rules get echoed. You can vary this by adding
different macros if you need varying amounts of output, much more
flexible and is accomplished without any software change.
