This patch add the support for --debug=c and --debug=e to make
this option when activated will trace in stdout the activity of $(call and $(eval in the Makefile
The trace use the format:
### xxx -->
### xxx <--
the number of space before ### is at least 1 and increase with the nesting of eval/call
usage: make --debug=c,e
