Have you looked at the --trace flag, introduced in GNU make 4.0?
>From the NEWS file:
* New command line option: --trace enables tracing of targets. When enabled
the recipe to be invoked is printed even if it would otherwise be suppressed
by .SILENT or a "@" prefix character. Also before each recipe is run the
makefile name and linenumber where it was defined are shown as well as the
prerequisites that caused the target to be considered out of date.
I do not notice that in 4.0, it has --trace flag. I only check 3.81 version.
Thanks for your info!
