I suggest defining "-v" as a "verbose" flag.  It will not do much for now,
but could be made to do more later.  (See other thread about "-v" cancelling
the effect of "@" or .SILENT rules.)

Then let "-v -V VARNAME" mean "verbosely display the value of ${VARNAME)".
The output could be something like this:

	$ cat Makefile
	FOO=fu
	BAR=bar
	FUBAR=${FOO} ${BAR}
	$ make -V FUBAR
	${FOO} ${BAR}
	$ make -v -V FUBAR
	variable: FUBAR
	value:    ${FOO} ${BAR}
	expanded: fu bar

I prefer not to use "-E" (as was suggested in another message), because
it seems to be a waste of precious option letters.
