scummvm/base/commandLine.cpp
Le Philousophe bffb6e244a BASE: Allow platforms to not include the help messages 
This allows to save some space on constrained devices which still allow
for command line.
Enable this space saving on DS and enable back command line support.
Cleanup old workaround for 3DS.
