This updates the powerpc code to use the CONFIG_GENERIC_CMDLINE
option.

This includes a scripted mass convert of the config files to use
the new generic cmdline. There is a bit of a trim effect here.
It would seems that some of the config haven't been trimmed in
a while.

The bash script used to convert is as follows,

if [[ -z "$1" || -z "$2" ]]; then
echo "Two arguments are needed."
exit 1
fi
mkdir $1
cp $2 $1/.config
sed -i 's/CONFIG_CMDLINE=/CONFIG_CMDLINE_BOOL=y\nCONFIG_CMDLINE_PREPEND=/g' $1/.config
make ARCH=$1 O=$1 olddefconfig
make ARCH=$1 O=$1 savedefconfig
cp $1/defconfig $2
rm -Rf $1
