Stefan Reinauer 0867062412 This patch unifies the use of config options in v2 to all start with CONFIG_
It's basically done with the following script and some manual fixup:

VARS=`grep ^define src/config/Options.lb | cut -f2 -d\ | grep -v ^CONFIG | grep -v ^COREBOOT |grep -v ^CC`
for VAR in $VARS; do
	find . -name .svn -prune -o -type f -exec perl -pi -e "s/(^|[^0-9a-zA-Z_]+)$VAR($|[^0-9a-zA-Z_]+)/\1CONFIG_$VAR\2/g" {} \;
done
