Comment (by arlolra):

 Attached is a patch to dcf's snowflake fork of `tor-browser-bundle` from
 #19001 that applies my libwebrtc patch, linked to above.

 Some bundles built with it can be found here:
 https://paganini.erinn.org/~arlolra/snowflake/20160813-6.5a1-d499d997/

 It reduces the size (on Linux) of `snowflake-client` from

 {{{
 15746976 Jan  1  2000 snowflake-client
 }}}

 to

 {{{
  9717904 Jan  1  2000 snowflake-client
 }}}

 so, not insignificant.  However, the tarred bundles only go from

 {{{
 75344292 Aug  6 16:49 tor-browser-linux32-6.5a1_en-US.tar.xz
 73896836 Aug  6 17:17 tor-browser-linux64-6.5a1_en-US.tar.xz
 }}}

 to

 {{{
 73548680 Aug 13 23:49 tor-browser-linux32-6.5a1_en-US.tar.xz
 72283512 Aug 13 23:49 tor-browser-linux64-6.5a1_en-US.tar.xz
 }}}
