PATCH 1/1 version_autogenerated.h: use printf rather than echo -n

Some systems are dumb and do not implement the -n flag to echo (like OS X). Convert the Makefile to use printf as this should work everywhere.

i realized this may break if the setlocalversion generates a space ... but i dont think that's possible ? if it is, then we should quote the $(shell ...) -mike

I added quotes, just to be sure.
