Add an `AM_V_PRINTF` variable to control whether `printf` is called.
Normally `AM_V_*` variables work by prepending
@echo blah;
to a whole rule to replace the usual output with something briefer.
Since, in this case, the aim is to suppress `printf` commands _within_ a
rule, `AM_V_PRINTF` works be prepending `:` to the `printf` command.
