Anobody have an ellegant solution to force the rebuild of all sub-makefiles if 
the main
project makefile has been changed ?
The main makefile calls envokes makefiles in other directories using $(MAKE). 
main makefile defines some options (Such as MCU) that should result in a 
of all the libraries as well. Curently I use make clean;make all to do this, 
but I have 
forgotten to do this in the past when I changed the target MCU. The problem is 
code built for say an ATMega16 works 99% for an ATMega32, so if one forgets to
rebuild the libraries for the new MCU, one can end up with very strange errors.
