After switching my development environment to a MacMini and using the ELDK 4.0 
I discovered that my examples for building using a cross-compiler for my 
PPC405 target were not correct. (Maybe a few of my previous problems were 
caused by not correctly specifying the target ARCH.)

Also I would like to adapt and document the examples/common/Makefile to the 
needs for cross-compiling (KSRC/XENOCONFIG/DESTDIR useage). Also I added a 
target "install" to copy the generated application to $(DESTDIR)/usr/xenomai.

Could someone please commit these (or a improved version of it) patches?

Thanks in advance
