I still think we should build this by default on the bots to stop it
regressing...

Yeah...  we definitely want to get there. I think the concern right now is that
we don't want developers working in base or ipc (for example) to have to worry
about our weird little file in ppapi.

When we have the gyp features we need, our build config will be in the
appropriate directory (e.g., we'll just exclude the right files from
base/base.gyp when in an untrusted build). I think that's when we'll get rid of
this flag.

Isn't the convention that '_untrusted' is a suffix, to indicate that this is
just part of the ppapi proxy?  That would match the gyp file's name.

I didn't know we had a convention, but that works for me. Done.

I should mention I swapped "ppapi" and "ipc" while I was at it... I think it's a
better name now, thanks.
