This can get pretty tricky, no doubt.

The simplest answer is to replace your $(eval ...) functions with
$(info ...) functions, at strategic places.  Then make will print out
EXACTLY what it would expand as the argument to call.  You can do
similar things with $(call ...) if you like.

For deep nesting this can get tricky.


Another option is to use the GNU make debugger; I've not used it much
myself and I'm not sure what version of GNU make is currently supported,
but you can find out more here:

http://bashdb.sourceforge.net/remake/

There's also a make debugger which is really just a suite of make
functions, rather than a separate program like remake; you can learn
more about that here:
