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  prerequisites that caused the target to be considered out of date.
