Is there a way to get the name of the makefile where a make variable was defined?

For debugging purposes, when there are many make file inclusions, it's useful to print the full path of the makefile where a particular variable in the current makefile was first defined. Is there a way to do that?

Just run make -p. Make will print its internal database including all targets and variables that were seen along with the filename and linenumber where they were set.

This might be tedious but you could go to each makefile and echo the makefile's location and filename. Then you can go on to print when a variable was defined as the makefile runs. Here is another post that goes more into detail with printing variables.
