The content/ directory is not supposed to have references to NaCl in it.  Given
that constraint, I'm not sure there is a way to forward this through to
nacl_helper as a command line argument.

Another way to forward this option through is to add it to 'struct
NaClStartParams' (from components/nacl/common/nacl_types.h), which
nacl_listener.cc receives.  nacl_process_host.cc can set the new field from the
command line option.

(In a later CL, nacl_process_host.cc can receive this option from the plugin, so
using NaClStartParams is the right direction to go in.)

Great to know. Done.
