A teammate wasn't sure how to toggle is_chromeos, I'm hoping that this would
have helped.

Perhaps there is a way to set the context for these internal args so that they
get the existing short help strings instead? I didn't look to see how that
works.

LGTM but this will not affect is_chromeos which is neither internally set nor a
build argument.

Sadly no, but hopefully it will help find |target_os|.
