Title: Make exports

The Makefiles of the application should be "friendly".
No "unfriedly" `export` should be needed.

This PR accumulates all the exported standard Makefile variables in one place for enhanced visibility.
It is put at the end of `Makefile.include` so it won't break `?=` assignments.
