can nacl just be treated as another platform aside to mac/linux etc? In that
case we don't need a separated gyp for nacl as lot of parts are duplicated to
libjingle.gyp in this file.

[Sergey Ulanov, 2014/02/21 00:48:00]

No, unfortunately it doesn't work this way. I think proper solution would be to
support a nacl in the 'toolset' parameter (see crbug.com/120214), but currently
GYP doesn't support it, and we need separate set of targets for NaCl. All other
NaCl targets are compiled in the same way (e.g. see base_untrusted.gyp).
